…they shall not depart from Me – Jeremiah 32:40

There moves in our hearts a deep sense of grateful obligation. God is so good to me; how can I sin? He loves me so, how can I vex Him? He favours me so greatly from day to day that I cannot do that which is contrary to His will. Did you ever receive a choice and special mercy? It has often fallen to my lot; and when the tears have been in my eyes at the sight of so great a favour, I have felt that if a temptation came to me, it would come at a time when I had neither heart, nor eye, nor ear for it. Gratitude bars the door against sin. Great love received overthrows great temptation to wander. Our cry is, “The Lord bathes me in His love, He indulges me with the nearest and dearest fellowship with Himself, and how can I do this great wickedness, and sin against God?” Loved of Him so specially, and united to Him by an everlasting covenant, how can we fly in the face of love so wonderful? Surely, we can find no pleasure in offending so gracious a God; but it is our joy to do His commandments, hearkening unto the voice of His word.

See, beloved, this perseverance of the saints, is perseverance in holiness: “They shall not depart from Me.” If the grace of God has really changed you, you are radically and lastingly changed…The work that is done in regeneration is not a temporary work, by which a man is, for a time, reformed; but it is an everlasting work, by which the man is born for heaven. There is a life implanted at the new birth, which cannot die, for it is a living and incorruptible seed, which liveth and abideth for ever. Grace will go on working in a man until it leads him to glory. ~ C.H. Spurgeon
