1 Thessalonians 1:5-6; 1 Thessalonians 4:8; 1 Thessalonians 5:19; 1 Thessalonians 5:23

5 for our gospel did not come to you in word only, but also in power and in the Holy Spirit and with full conviction; just as you know what kind of men we proved to be among you for your sake. 6 You also became imitators of us and of the Lord , having received the word in much tribulation with the joy of the Holy Spirit,
8 So, he who rejects this is not rejecting man but the God who gives His Holy Spirit to you.
19 Do not quench the Spirit;
23 Now may the God of peace Himself sanctify you entirely; and may your spirit and soul and body be preserved complete, without blame at the coming of our Lord Jesus Christ.
