From God's Word
May God himself, the God of peace, sanctify you through and through. May your whole spirit, soul, and body be kept blameless at the coming of our Lord Jesus Christ.
1 Thessalonians 5:23
As obedient children, do not conform to the evil desires you had when you lived in ignorance. But just as he who called you is holy, so be holy in all that you do; for it is written: "Be holy, because I am holy."
1 Peter 1:14-16
For God did not call us to be impure, but to live a holy life.
1 Thessalonians 4:7
Therefore, since we have these promises, dear friends, let us purify ourselves from everything that contaminates body and spirit, perfecting holiness out of reverence for God.
2 Corinthians 7:1
Make every effort to live in peace with everyone and to be holy; without holiness no one will see the Lord.
Blessed are those whose ways are blameless, who walk according to the law of the Lord.
