It might be supposed that Adam had no other law to obey save the single one of not eating from the forbidden tree, but that would be a simplistic view. Adam was under the Moral Law of God, the Ten Commandments, as a moment’s thought will confirm. Suppose Adam built an idol in the garden to worship, or suppose he strangled Eve! Would God have said, “Oh, that’s alright, Adam, just as long as you don’t eat the fruit!” The very thought is absurd. It is true that Adam could not have coveted his neighbour’s ox or his ass since he had no neighbours, but he certainly coveted that which God had denied to him and stole it to his own inestimable loss and that of his posterity. ‘Therefore, just as through one man sin entered the world, and death through sin, and thus death spread to all men, because all sinned’ (Romans 5:12 ).
There is no doubt but that the Covenant of Works was a gracious covenant. God was under no obligation to do anything for Adam, yet He gave him a wife, placed him in a beautiful garden with only light tasks to perform (there were no weeds before the Fall- Gen 3:17-18 ) and gave him dominion over all the rest of creation. However, there is no mention of mercy in the covenant. Adam is warned, “In the day you eat of it, you shall surely die.” To put it another way, “Do this and live.” Adam’s privileges were dependant on his obedience. Yet he was well able to perform this obedience. God had made him entirely righteous; otherwise He could not have pronounced the whole of creation ‘very good’ (Gen 1:31 ).
Yet Adam was not in the most gracious state possible. Though he had been created sinless, he was still able to sin; he stood or fell by his own actions. This has led many theologians to postulate that Adam was on probation; had he not sinned, they say, God would have promoted him to a still more gracious position in which he would have been unable to sin. We read in Gen 2:9b of the ‘Tree of Life.’ It is suggested that at the end of their probation, Adam and Eve would have been permitted to eat from this tree and their eternal lives would have been assured. Certainly, after their fall, the way to the tree of life was lost to mankind (Gen 3:24 ) and is not heard of again until Rev 2:7 and 22:2 where it is seen as the reward for those who persevere, the very thing that Adam and Eve failed to do. This idea is quite attractive and may be correct, but we cannot insist upon it because it is a conjecture and is not clearly found in the word of God. If we want to remain true to the Baptist Confession, we must take all our doctrine from the Bible and eschew all conjecture.
