…I will not turn away from them, to do them good… – Jeremiah 32:40

Please notice the terms here: the Lord does not merely say, “I will not turn away from them,” but, “I will not turn away from them, to do them good.” He will not cease to work good for His chosen. The Lord is always doing His people good; and here He promises that He will never leave off blessing them. Not only will He always love them, but He will always prove His love by active kindness and blessing. He is pledged to continue the gifts and work of His goodness…let us remember that there is no valid reason why He should turn away from them to do them good. You remind me of their unworthiness. Yes, but observe that when He began to do them good they were as unworthy as they could possibly be. He began to do them good when they were “dead in trespasses and sins.” He began to do them good when they were enemies, rebels, and under condemnation. When first the sinner feels the movement of divine love upon his heart, he is in no commendable state. In some cases, the man is a drunkard, a swearer, a liar, or a profane person. In certain cases, the man has been a persecutor like Manasseh or Saul. If God left off blessing us because He could see no good in us, why did He begin to do us good when we were without desire towards Him? We were a mass of misery, a pit of wants, and a dunghill of sins when He began to do us good. Whatever we may be now, we are not otherwise than we were when first He revealed His love towards us. The same motive which led Him to begin leads Him to continue; and that motive is nothing but His grace….He entered into a covenant that He would not turn away from us, to do us good; and no circumstance has arisen, or can arise, which was unknown to Him when He thus pledged His word of grace. ~ C.H. Spurgeon
