Why This Matters
When sin entered the world in Genesis 3, death came along with it. God warned that this would happen in His prohibition against eating of the tree of the knowledge of Good and Evil in Genesis 2:15-17:
15 The Lord God took the man and put him in the garden of Eden to work it and keep it. 16 And the Lord God commanded the man, saying, “You may surely eat of every tree of the garden, 17 but of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat[d] of it you shall surely die.”
This terrible doom fell on mankind in the very next chapter, where God curses the serpent, the woman, and all of mankind after the deliberate disobedience of our first ancestors in Genesis 3:19
"By the sweat of your face
you shall eat bread,
till you return to the ground,
for out of it you were taken;
for you are dust,
and to dust you shall return.”
However, right in the middle of this sentence of doom, God made a promise to conquer the presence of evil that Satan introduced into the lives of men in verse 15:
"I will put enmity between you and the woman,
and between your offspring and her offspring;
He shall bruise your head,
and you shall bruise His heel.”
So sin brings death, and God promised to break the curse, and he promised to do so by sending a "He." He would break the curse and would suffer in the process. You can read the whole of the Old Testament looking for who "He" is. Is "He" Abraham? No. Isaac? Certainly not! Jacob? No. David was a type but he suffered for his own sins. Solomon was wise but fell away from the Lord. Josiah was perhaps the most righteous king, but even he dealt with pride and a lack of faith. One after another, the maybe-messiahs fall short.
What is needed is someone who can take on the sins of the world because they don't have their own sins. What is needed is someone to step into the debt of death and pay it vicariously for others rather than satisfying their own appointment with the grave. What is needed is someone who cannot be conquered by death so that, once they walk through it, they will emerge from it victorious, defeating the reality of death once and for all. What is needed is someone who is simultaneously God and Man. Only a man can pay the debt of death that all men owe. Only God can shake off the graveclothes and emerge victorious.
Only Jesus can be that Savior, and He is! He is the "He" we've all been waiting for!
