(1.) They differ in their terms. The absolute promises say, I will, and you shall: the other, I will, if you will; or, Do this, and thou shalt live (Jer 4:1; 31:31-33; Eze 18:30-32; 36:24-34; Heb 8:7-13; Matt 19:21).
(2.) They differ in their way of communicating of good things to men; the absolute ones communicate things freely, only of grace; the other, if there be that qualification in us, that the promise calls for, not else.
(3.) The absolute promises therefore engage God, the other engage us: I mean, God only, us only.
(4.) Absolute promises must be fulfilled; conditional may, or may not be fulfilled. The absolute ones must be fulfilled, because of the faithfulness of God; the other may not, because of the unfaithfulness of men.
(5.) Absolute promises have therefore a sufficiency in themselves to bring about their own fulfilling; the conditional have not so. The absolute promise is therefore a big-bellied promise, because it hath in itself a fullness of all desired things for us; and will, when the time of that promise is come, yield to us mortals that which will verily save us; yea, and make us capable of answering of the demands of the promise that is conditional.
4. Wherefore, though there be a real, yea, an eternal difference, in these things, with others, betwixt the conditional and absolute promise; yet again, in other respects, there is a blessed harmony betwixt them; as may be seen in these particulars. The conditional promise calls for repentance, the absolute promise gives it (Acts 5:31). The conditional promise calls for faith, the absolute promise gives it (Zeph 3:12; Rom 15:12). The conditional promise calls for a new heart, the absolute promise gives it (Eze 36:25,26). The conditional promise calleth for holy obedience, the absolute promise giveth it, or causeth it (Eze 36:27).
5. And as they harmoniously agree in this, so again the conditional promise blesseth the man, who by the absolute promise is endued with its fruit. As, for instance, the absolute promise maketh men upright; and then the conditional follows, saying, “Blessed are the undefiled in the way, who walk in the law of the Lord” (Psa 119:1). The absolute promise giveth to this man the fear of the Lord; and then the conditional followeth, saying, “Blessed is every one that feareth the Lord” (Psa 128:1). The absolute promise giveth faith, and then this conditional follows, saying, “Blessed is she that believed” (Zeph 3:12; Luke 1:45). The absolute promise brings free forgiveness of sins; and then says the condition, “Blessed are they whose iniquities are forgiven, and whose sins are covered” (Rom 4:7). The absolute promise says, that God’s elect shall hold out to the end; then the conditional follows with his blessings, “He that shall endure unto the end, the same shall be saved” (1 Peter 1:4-6; Matt 24:13).
Thus do the promises gloriously serve one another and us, in this their harmonious agreement.
Now, the promise under consideration is an absolute promise. “All that the Father giveth me shall come to me.”
This promise therefore is, as is said, a big-bellied promise, and hath in itself all those things to bestow upon us that the conditional calleth for at our hands. They shall come! Shall they come? Yes, they shall come. But how, if they want those things, those graces, power, and heart, without which they cannot come? Why, Shall-come answereth all this, and all things else that may in this manner be objected. And here I will take the liberty to amplify things.
