What does the Bible say about the purpose of sin entering the world?

According to Scripture, the entrance of sin into the world was part of God's infinitely wise and eternal plan. While God could have prevented sin, He ordained it as the means through which His great grace would be made known. Without Adam's fall, there would be no necessity for the justifying grace of God, forgiveness, or the redemptive work of Christ. The necessity of grace arises from the reality of human sinfulness, which highlights God's mercy and His glory in the salvation of sinners. As a result, God uses the backdrop of man's guilt and corruption to fully display the beauty and magnificence of His grace and the need for Christ's sacrifice.
