1 Thessalonians 2:7-13

But we were gentle among you, even as a nurse cherisheth her children: so being affectionately desirous of you, we were willing to have imparted unto you, not the gospel of God only, but also our own souls, because ye were dear unto us. For ye remember, brethren, our labour and travail: for labouring night and day, because we would not be chargeable unto any of you, we preached unto you the gospel of God. Ye are witnesses, and God also, how holily and justly and unblameably we behaved ourselves among you that believe: as ye know how we exhorted and comforted and charged every one of you, as a father doth his children, that ye would walk worthy of God, who hath called you unto his kingdom and glory. For this cause also thank we God without ceasing, because, when ye received the word of God which ye heard of us, ye received it not as the word of men, but as it is in truth, the word of God, which effectually worketh also in you that believe.
