6Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.
7And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.
1 Thessalonians 3:12-13–
12And the Lord make you to increase and abound in love one toward another, and toward all men, even as we do toward you:
13To the end he may stablish your hearts unblameable in holiness before God, even our Father, at the coming of our Lord Jesus Christ with all his saints.
