When life doesn't make sense, we often struggle with four fundamental problems that Solomon identified in Ecclesiastes. First, the problem of injustice - why wickedness exists even in systems designed for justice. Our innate moral compass and outrage at unfairness actually point to God's existence, as C.S. Lewis noted that we wouldn't recognize a crooked line without some concept of a straight one. While social reforms may help temporarily, only the gospel can truly change hearts and bring lasting justice. Second, we face the problem of death - the sobering reality that all humans return to dust regardless of status or achievement. Contemplating our mortality helps us prioritize what truly matters instead of wasting time on trivial concerns. Unlike the atheist conclusion that death is simply the end, Christianity offers hope that death is real but not final. Third, we wonder about the afterlife - is heaven real? The historical fact of Jesus' resurrection provides our proof and foundation for hope. Finally, we struggle with enjoying the present without falling into escapism. Many people fill their calendars with endless activities, creating no margin to contemplate deeper questions or develop dependence on God. True joy isn't found in busyness but in relationship with Jesus. These challenges aren't random but clues pointing us to deeper truths. When angry about injustice, let it point to God's perfect justice. When fearing death, recognize your need for resurrection power. When uncertain about eternity, strengthen your faith in Jesus' promises. And when joy feels fragile, seek the unshakable joy of God's presence. At the cross, the greatest injustice became the greatest act of love, defeating death and securing eternal joy.
