Paul greatly loved the churches he visited. In his letters he would let the people know he was praying the best for them.
2 Thessalonians 3:1-5
3 Finally, dear brothers and sisters, we ask you to pray for us. Pray that the Lord’s message will spread rapidly and be honored wherever it goes, just as when it came to you. 2 Pray, too, that we will be rescued from wicked and evil people, for not everyone is a believer. 3 But the Lord is faithful; he will strengthen you and guard you from the evil one. 4 And we are confident in the Lord that you are doing and will continue to do the things we commanded you. 5 May the Lord lead your hearts into a full understanding and expression of the love of God and the patient endurance that comes from Christ.
