1 Thessalonians 5:23-24
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. The one who calls you is faithful, and he will do it.
2 Timothy 2:15
Do your best to present yourself to God as one approved, a worker who does not need to be ashamed and who correctly handles the word of truth.
