Here in Genesis 22 the Spirit of God is continuing a theme, an all important theme, that will give a greater degree of light to those, who like Abraham, were waiting on God to fulfill the promise of a Messiah, even the Seed of the woman. Here in this glorious chapter we have what is perhaps father Abraham's greatest test of faith.
God knew his servant Abraham and the measure of his faith, and when God was finished with him, Abraham knew it too.
