1 Thessalonians

But behold, I say unto you, that ye must pray always, and not faint; that ye must not perform any thing unto the Lord, save in the first place ye shall pray unto the Father in the name of Christ, that he will consecrate thy performance unto thee, that thy performance may be for the welfare of thy soul.

And they did admonish their brethren; and they were also admonished, every one, by the word of God, according to his sins, or to the sins which he had committed; being commanded of God to pray without ceasing, and to give thanks in all things.
