Why do Christians experience afflictions in life?

In Psalm 90:15, Moses reflects on the afflictions faced by believers, understanding that these trials serve a divine purpose. Afflictions can lead to greater dependence on God's mercy and grace, teaching us lessons we might not learn in times of ease. The difficulties we face in life often counterbalance the joys and blessings we receive, as highlighted in verses 15-16. This balance demonstrates God's providence and the way He uses all experiences to cultivate a deeper faith and reliance on Him, ultimately leading to a fuller appreciation of His grace and glory.
