How does God use sorrow and loss to mature our faith? Can we trust Him day by day when His purposes are hidden in pain? We reflect on the life of Karolina Sandell-Berg as a living expression of Jesus’ call in Matthew 5:48 to grow into spiritual maturity. Through frailty, suffering, and the sudden loss of her beloved father, Karolina turned to Christ rather than away from Him, allowing trials to deepen her trust in God’s wise and loving care. From bitter waters, God brought sweet songs—most notably Day by Day—reminding us that the Lord uses hardship to perfect our faith, shaping us through suffering to rest in His promises until we stand with Christ at last.
