I learned this from Chuck Missler, a fantastic Bible scholar.
One of the first pictures we find of Christ in the Old Testament is in the book of Genesis (surprise!). After the creation story, we are given a genealogy.
The list begins with Seth, which means “Appointed.” Enosh, his son, means “Mortal;” and his son, Kenan, means “Sorrow.” His son Mahalalel, means “The Blessed God.” He named his boy Jared which means “Came Down,” and his boy, Enoch, means “Teaching.” Methuselah means “His death shall bring;” Lamech means “Strength,” and Noah, “Comfort.” Now put that all together:
God has Appointed that Mortal man shall Sorrow;
but The Blessed God, Came Down, Teaching,
that His Death Shall Bring,
Strength and Comfort.
There we have it – the Gospel in Genesis 1 and our first hidden picture revealed.
