1 Thessalonians 2:8-12

even so, being affectionately desirous of you, we were well pleased to impart unto you, not the gospel of God only, but also our own souls, because ye were become very dear to us. For ye remember, brethren, our labor and travail: working night and day, that we might not burden any of you, we preached unto you the gospel of God. Ye are witnesses, and God also, how holily and righteously and unblamably we behaved ourselves toward you that believe: as ye know how we dealt with each one of you, as a father with his own children, exhorting you, and encouraging you, and testifying, to the end that ye should walk worthily of God, who calleth you into his own kingdom and glory.
