It’s all of God
1 Thessalonians 5:23–28
23 Now may the God of peace himself sanctify you completely, and may your whole spirit and soul and body be kept blameless at the coming of our Lord Jesus Christ. 24 He who calls you is faithful; he will surely do it.
25 Brothers, pray for us.
26 Greet all the brothers with a holy kiss.
27 I put you under oath before the Lord to have this letter read to all the brothers.
28 The grace of our Lord Jesus Christ be with you.
