1 John 2:24

"Let that therefore abide in you, which ye have heard from the beginning. If that which ye have heard from the beginning shall abide in you, ye also shall abide in the Son, and in the Father. And this is the promise that He hath promised us." For haply thou mightest ask about the wages, and say, Behold, "that which I have heard from the beginning I keep safe in me, I comply therewith; perils, labors, temptations, for the sake of this continuance, I bear up against them all: with what fruit? what wages? what will He hereafter give me, since in this world I see that I labor among temptations? I see not here that there is any rest: mere mortality weigheth down the soul, and the corruptible body presseth it down to lower things: but I bear all things, that "that which I have heard from the beginning" may "remain" in me; and that I may say to my God, "Because of the words of Thy lips have I kept hard ways." Unto what wages then? Hear, and faint not. If thou wast fainting in the labors, upon the promised wages be strong. Where is the man that shall work in a vineyard, and shall let slip out of his heart the reward he is to receive? Suppose him to have forgotten, his hands fail. The remembrance of the promised wages makes him persevering in the work: and yet he that promised it is a man who can deceive thine expectation. How much more strong oughtest thou to be in God's field, when He that promised is the Truth, Who can neither have any successor, nor die, nor deceive him to whom the promise was made!
