For God's will was for us to be made holy by the sacrifice of the body of Jesus Christ, once for all time.
Hebrews 10:10, NLT
Note that God's will is for us to be made holy. "Me, holy?" you say. "How?" By our righteous deeds? No! Only by the sacrifice of Jesus' body on the cross. We cannot nor will not ever be able to earn it. Jesus did it for us, and our part is to BELIEVE it and RECEIVE it!
