Because Jesus Christ lived a sinless life, His blood shed on the cross of Calvary is 100% sufficient to cleanse us of all sins when appropriated individually through repentance and faith. Jesus allowed Himself to be punished for the sins we have committed, enabling all who believe to be freed from the penalties of sin. (I John 1:7; Revelation 1:5, 5:9; Colossians 1:20; Romans 3:10-12 & 23; 5:9; John 1:29)
