“The heart knows its own bitterness…” – Proverbs 14:10

Social media has immense power to cultivate bitterness in the human soul. For most of history, people wrestled primarily with local frustrations, local enemies, and local envy. Now, through mass media, we are exposed daily to the anger, success, outrage, opinions, and conflicts of millions of people. An individual involved with social media no longer deals merely with interpersonal relationships, but with a digital world overflowing with shallow ones. With more content comes more opportunities for envy, resentment, anxiety, outrage, and despair. We used to envy our neighbors; now we envy the world.

Bitterness is not stagnant. It spreads, deepens, and consumes. It can harden into anger, and anger can eventually erupt into retaliation, sometimes violent. One only needs to watch the nightly news to see protests devolving into chaos and rage. Often, the emotional fuel behind such unrest is cultivated online long before it appears in the streets. Sadly, online bitterness rarely stays online. Rage formed digitally eventually spills into real life. A heart shaped by contempt will eventually speak, act, and live contemptuously.

But this problem is not merely “out there.” Bitterness is not simply something we fight in others; it exists in every human heart, including my own. The battle against bitterness is not first waged online or politically, but spiritually within our own souls. Scripture paints a picture in which each of us must confront the roots of bitterness growing within us and bring them before God for healing.

Every created thing experiences some form of bitterness, whether physical suffering, emotional anguish, spiritual emptiness, or sin itself. The world is fallen, and everything it touches tastes bitter. Bitterness entered creation in the Garden of Eden when Adam and Eve ate from the tree of the knowledge of good and evil. The fruit may have tasted sweet upon their lips, but it left bitterness in the human soul. After the fall came suffering, death, shame, pain, and alienation from God. Sin is bitterness in our spirit, pain is bitterness in our bodies, and suffering is bitterness in our souls.

Evil is not merely described in Scripture as lawbreaking, but as a bitter poison that corrodes the human heart. Proverbs warns of the forbidden path that “at the last is bitter as wormwood” (Proverbs 5:4), and Isaiah pronounces judgment upon those who “call evil good and good evil…who put bitter for sweet and sweet for bitter” (Isaiah 5:20). Sin always promises sweetness on the lips before becoming poison in the stomach.

More than proverbial wisdom, bitterness forms a thematic thread running from Genesis to Revelation. Exodus, Lamentations, the Psalms, Ecclesiastes, and many New Testament passages all develop this imagery. During Passover, God commanded Israel to eat bitter herbs so they would remember the bitterness of slavery in Egypt. Job and the prophet Jeremiah embody bitterness through suffering and lament. In the New Testament, the apostle Paul repeatedly warns the Church to “put away all bitterness,” while the apostle John records in Revelation that one of God’s judgments upon the earth is bitter water.

God, in His salvation, delights in taking what is bitter and making it sweet. He heals poisoned things. And I believe we see this beautifully in two biblical stories: Moses and Naomi.

Moses and the Israelites

After Israel fled Egypt and crossed the Red Sea, God immediately began providing for His people. He gave them manna from heaven, quail, and water in the wilderness. One famous example appears in Exodus 15.

Moses writes:

“Israel set out from the Red Sea, and they went into the wilderness of Shur. They went three days in the wilderness and found no water. When they came to Marah, they could not drink the water of Marah because it was bitter.”[1]

This passage reveals something deeply true about the human heart: experiencing bitterness can produce bitterness within us. The bitter waters exposed the bitterness already growing in the hearts of the Israelites. Their desire for water was good, but when they could not satisfy that desire, they grumbled against both Moses and God.

The story continues as God instructs Moses to throw a piece of wood into the water. Miraculously, the bitter waters became sweet and drinkable. Even in the midst of Israel’s grumbling, God provides healing.

Naomi and Ruth

The book of Ruth examines the lives of two women devastated by suffering, death, and displacement. Though Ruth gives the book its name, Naomi stands at the center of its emotional story.

Naomi and her family flee Israel during a famine and settle in Moab. There they experience stability and happiness. Her sons marry local women, including Ruth. Then tragedy strikes. Naomi’s husband and sons die, leaving her widowed, childless, and hopeless in a foreign land.

Naomi decides to return home to Bethlehem. She urges her daughters-in-law to remain behind and rebuild their lives. Ruth famously refuses:

“Where you go I will go, and where you lodge I will lodge. Your people shall be my people, and your God my God.”[2]

When Naomi arrives home, the people recognize her and greet her warmly. But Naomi responds with astonishing grief:

“Do not call me Naomi; call me Marah, for the Almighty has dealt very bitterly with me.”[3]

This moment is devastating. Naomi’s name means “pleasant.” She is so consumed by sorrow that she renames herself “Bitter.” Her suffering becomes her identity.

Yet God does not leave Naomi there.

Through Ruth’s faithful love, God restores Naomi’s joy. Ruth marries Boaz, redemption enters the family line, and Naomi once again experiences fullness instead of emptiness. The book closes not with despair, but celebration:

“Blessed be the LORD, who has not left you this day without a redeemer…”[5]

Bitter Marah becomes pleasant Naomi once again.

Moses and Naomi Explained

The similarities between these stories are striking. Both involve something once pleasant becoming bitter because of outside circumstances. The waters of Marah became bitter. Naomi became bitter. Both, in turn, became bitter toward others. The Israelites refused to drink the water, and Naomi lashed out toward God and her friends.

Yet neither story ends in bitterness.

The waters are healed through a tree. Naomi is healed through the loving faithfulness of Ruth. Both become sources of refreshment and joy once again.

These stories reveal a simple yet profound truth: we need something beyond ourselves to heal the bitterness within us. We need a tree. We need a Ruth. Ultimately, we need Jesus.

We are like the waters of Marah and like Naomi. We become bitter toward God because of suffering, pain, disappointment, and loss. We become bitter toward neighbors, enemies, friends, and family. We feel envy, resentment, anger, and despair festering within us. Bitterness is not pleasant. We need healing.

Jesus Christ is the true and better fulfillment of both stories.

Jesus, through His life, crucifixion, and resurrection, heals human bitterness at its deepest root. He dies upon a bitter tree and transforms it into the instrument of salvation. He takes the bitterness of sin, suffering, and death upon Himself and offers us His sweetness in return.

Gregory of Nyssa saw the tree at Marah as a picture of the cross itself:

“But if the wood be thrown into the water… then the virtuous life, being sweetened by the hope of things to come, becomes sweeter and more pleasant…”

Jesus does not merely save us from physical death. He heals the bitterness and hatred hidden deep within the human heart. How beautiful is Christ. He allowed Himself to be cut down in bitterness so that we might become joyful, whole, and pleasant once again.

Jesus not only saves us from the bitterness of sin, death, and the devil, but He also shows us how to overcome bitterness in our own hearts. Through the Holy Spirit, Christ is shaping us to become more like Him. Jesus was betrayed, beaten, mocked, and crucified. The very people He healed and loved cried out for His death. His closest friends abandoned Him. And in His suffering, Jesus cried out, “My God, my God, why have you forsaken me?” [7]

Yet even in unimaginable pain, Jesus responded not with bitterness, but with grace. To those crucifying Him, He prayed, “Father, forgive them.” [8] To the disciples who abandoned Him, He offered peace and restoration. [9] To the Father, He entrusted His spirit completely. [10]

Jesus met bitterness with love, rejection with mercy, and suffering with trust. Instead of allowing evil and pain to poison His soul, Christ overcame them through humble, self-giving love.

We need Jesus. We need His atonement, His Spirit, His joy, His example, and His life.

Jesus’ presence is nourishing, satisfying, and sweet. “Taste and see that the LORD is good” (Psalm 34:8). The Psalmist says God’s words are “sweeter than honey” (Psalm 119:103). Thomas Watson, the Puritan preacher, once wrote, “Till sin be bitter, Christ will not be sweet.” I understand what he’s saying, but I like that quote reversed: “Taste of Christ who is sweet, and your sin will be bitter.” We overcome bitterness by continually tasting the goodness of God in Jesus.

In an age shaped by outrage, algorithms, and endless online conflict, bitterness has become a kind of cultural currency. Social media rewards mockery, anger, resentment, and contempt. The modern world disciples people into outrage, teaching us to devour one another with cynicism and self-righteousness. But the Church must not drink from the same poisoned well.

Rather than bringing our bitterness before God for healing, we often numb it. We distract ourselves with entertainment, doomscrolling, outrage, pornography, consumption, politics, and endless noise. But numbed bitterness is still bitterness. Untreated bitterness does not disappear; it simply sinks deeper into the soul.

Experiencing bitterness need not result in becoming bitter.

When people mock you, slander you, or treat you with contempt, pray for them. When friends wound you or abandon you, forgive them. And when God feels distant—when heaven seems silent and your soul feels empty—place your life back into His hands, trusting that His love has not left you.

When the Church responds to suffering, anger, resentment, and evil with grace, peace, joy, and love, it becomes like the waters of Marah made sweet by God. Through the work of the Holy Spirit, Christians can become instruments of healing in the lives of others. Christ heals us not merely so we can become better individuals, but so we might become a blessing to the world around us.

If bitterness can spread, well, so can joy.

The world has tasted enough bitterness. Enough outrage. Enough contempt. The Church must become sweet again. Let us cling to Christ so deeply that our words become gentle, our lives become healing, and our presence becomes like cool water in a desert. Show the world the sweetness of the gospel and the goodness of the Triune God.
