Israel showed to be a faithless nation under many gods from the start of being a nation, because Israel lived in Egypt for many years and Egypt had many gods. Without a doubt, these gods were engraved in the minds and hearts of the sons of Jacob, resulting in their faithlessness to God. However, in spite of that, God’s covenant with Abraham and his descendants, stood. His covenant had a divine purpose beyond Israel’s understanding and time. It had its beginning at the Garden of Eden when God promised a Redeemer. He said, And I will put enmity between you and the woman and between your offspring and her Offspring; He will bruise and tread your head underfoot, and you will lie in wait and bruise His heel (Gen. 3:15). That was fulfilled almost two thousand years ago when YAHSHUA treaded Satan’s head underfoot by His death on the cross. Therefore, Satan stands condemned, judged and sentenced. To Abraham’s obedience God rendered his blessing upon his descendants. In his faithfulness, when he did not spare his son, but would have offered him as a sacrifice to God as he was told, God confirmed Abraham the covenant with blessings: In blessing I will bless you and in multiplying I will multiply your descendants like the stars of the heavens and like the sand on the seashore. And your Seed (YAHSHUA) will possess the gate of His enemies. And in your Seed [YAHSHUA] shall all the nations of the earth be blessed and bless themselves, because you have heard and obeyed My voice (Gen. 22: 17-18). So on that region of Moriah, where Abraham was tested, many years later YAHSHUA laid His life as a sacrifice to save the world through death on the cross.
