The eating of the forbidden fruit was a sin because it was a direct rejection to the only commandment God gave Adam and Eve “And the LORD God commanded the man, saying, 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” (Genesis 2:16,17). Eating of the fruit was rebellion against God’s law. The Bible says, “To him that knoweth to do good, and doeth it not, to him it is sin” (James 4:17). And “Sin is the transgression of the law” (1 John 3:4).
The very presence of this tree in the garden revealed that man was a free moral agent. Man’s service was not forced; he might either obey or disobey. The decision was his. The fruit itself was harmless. But God’s explicit commandment to refrain from eating it set this tree apart as the testing ground of man’s loyalty and obedience. Man could use freely of everything that was in the garden—except one tree. No other purpose, evidently, was to be served by refraining from eating the fruit of this tree than to give clear proof of allegiance to God.
By rejecting God’s command, Adam and Eve joined themselves with Satan and separated themselves from God (Isaiah 59:2). Satan planned for the couple to sin and then eat of the tree of life, and thus become immortal sinners. But God removed them from the garden to prevent such a tragedy “And the Lord God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever.” “So he drove out the man; and he placed at the east of the garden of Eden Cherubims, and a flaming sword which turned every way, to keep the way of the tree of life” (Genesis 3:22, 24).
