But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die. – Genesis 2:17
Then said I, Lo, I come. – Psalm 40:7
Man in the Garden of Eden had every advantage for obedience and life. He had a perfect nature, created without bias towards evil, and he was surrounded with every inducement to continue loyal to his Maker. He was placed under no burdensome law. The precept was simple and plain: “Of every tree of the garden thou mayest freely eat: but of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die.” Only one tree was reserved: all the rest were given up to be freely enjoyed. In a very short time-some think it was on the first day, but that we do not know, our mother Eve ate of the fruit, and father Adam followed her, and thus human probation ended in total failure. They were weighed in the balances, and found wanting: “Adam being in honor continued not.” At that point we read in the volume of the Book that the Seed of the woman should bruise the serpent’s head. Then our Redeemer said, “Lo, I come.” Hearken to me, my friend: you also have had your probation, as you have thought it to be. You quitted your father’s roof with every hope, your mother judged you to be of a most amiable character, and your friends expected to see in you one whose life would honor the family. You thought so yourself. Your probation has reversed that hope: you have turned out far other then you should have been; and looking back upon the whole of your life to this moment, you ought to be ashamed. It has been a terrible breaking down for you, and for all who know you; and you are sitting in this place feeling, “Yes, it is so; the tests have proved me to be as a broken reed. I am under condemnation by reason of my transgressions against God.” How rejoiced I am to tell you that, at such a time when you are conscious that you are a dead failure, Jesus says, “Lo, I come!” If you had not been a failure you would not have wanted Him, and He never comes as a superfluity; but now in your complete break-down you must have Him or perish, and in infinite pity He cries, “Lo, I come.” Is not this good news for you? Believe it and live. ~ C.H. Spurgeon
