What does the Bible say about suffering for sins?

In Lamentations 3:39, the prophet Jeremiah reminds us that a living man should not complain about punishment for his sins, as Christ has already borne that punishment on our behalf. When believers experience suffering, it is not a sign of God's punitive wrath, but rather a loving discipline meant to guide us back to Him. Our afflictions serve to strengthen our faith and reliance on God, as He draws us closer to Himself through these trials, illustrating His sovereignty over all circumstances.
