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.” (Genesis 3:15 ESV)
Promises
A chasm lurks between, “I might” and “I will.” “I will try,” is not in the same league as, “I will.” Every child knows the difference between “maybe,” and “yes.”
In the first book of the Bible, the first promise that God made to His people was the promise to fix what Adam broke. And that fixing would be done by a Messiah. Throughout the Old Testament, God described that Messiah in two ways.
The Messiah was described as divine (Daniel 7:3, and Micah 5:2).
The Messiah was described as human (Isaiah 7:15, Deuteronomy 18:16).
In order that both of these sets of prophecies be fulfilled, the Messiah had to somehow be both divine AND human.
And that is exactly what the incarnation was.
The Divine, becoming Human, without abandoning His Divinity.
The incarnation was necessary lest God be a liar.
And God is not a liar.
He broke the laws of the universe in that Messiah-birth. Think what He will do for you!
God kept His promises in the Incarnation.
