The believers must continue to trust God
13 We always thank God for you, our Christian friends that the Lord loves. We ought to thank God, because he has chosen to save you. God chose you to belong to him, as some of the first people that he would save. You believed God's true message. And God's Spirit makes you separate from things that are bad. 14 We told you God's good news. That is how God called you to come to him. He saved you so that you would join with our Lord Jesus Christ in heaven.
15 Because of that, our Christian friends, you must continue to trust Christ. Continue to believe the true things that we taught you. Those are the things that we told you when we were with you. We also wrote about them in our letter to you.
16 We ask our Lord Jesus Christ himself, and God, our Father, to help you. God has shown that he loves us very much. He has helped us to be brave and strong for all time. We continue to hope for the good things that will come. Yes, God has been very kind to us! 17 We pray that he will continue to help you and make you strong. Then you will always be able to do good things and to say good things.
