4 Bible Verses about Sinlessness

May the Lord strengthen your hearts so you will be [found] without just blame and holy, in the presence of our God and Father, when our Lord Jesus Christ returns with all of His holy ones [i.e., angels. See Mark 8:38; II Thess. 1:7].

And may God Himself, who gives peace, dedicate you completely, and may your spirit, soul and body [i.e., your entire person] be kept without just blame at [i.e., until] the return of our Lord Jesus Christ.

If we claim that we have not committed sins, we are [in effect] calling God a liar [i.e., because He says we have] and His word [i.e., the real truth about the matter] is not in our hearts.
