“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.” 1 Thessalonians 5:23-24
“He will do it.” God will sanctify us. We aren’t on a self-improvement program, rather we’re on a God-initiated and enabled sanctification program where we’re transformed into Christ’s image. This happens according to God’s timetable and agenda, not ours. We can trust God’s plan because we know he always working for our good (Romans 8:28).
