I like how he said to not do anything to quench the Holy Spirit. You know those few times when you are deep in prayer and you feel like God himself is just right there with you? Those are the times you are feeling the Holy Spirit. You can also sense the presence of the Holy Spirit at other times, too.
I also like how he asks the brethren in Thessalonica to pray for them. That shows that Paul was very humble, even though he was a strong leader.
The reference for this is 1 Thessalonians 5:14-25 found in the New Testament of the Holy Bible.
14 Now we exhort you, brethren, awarn them that are bunruly, ccomfort the dfeebleminded, esupport the fweak, be patient toward all men.
15 See that none arender bevil for evil unto any cman; but ever follow that which is good, both among yourselves, and to all men.
16 aRejoice evermore.
17 aPray without ceasing.
18 In every thing give athanks: for this is the will of God in Christ Jesus concerning you.
21 aProve all things; hold fast that which is good.
23 And the very God of peace asanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ.
