God commands Abraham to sacrifice his only son. We see:
How this was a test of Abraham’s faith - not so God would know the strength of it (since He knows all things) but so Abraham would see what was in his own heart and know the truth of his own trust in God
How this was a wonderful picture of Christ - we examine the strong parallels between this sacrifice and God’s sacrifice in much the same location of His one and only Son.
How God renewed His promises to Abraham on the basis of his faith - demonstrated in his actions during this trial. We remind ourselves that even this faith was a gift from God.
We are encouraged to trust God whatever trials He may send into our lives - to remember His faithfulness to all His promises. Those who do not know Him are urged to come to Christ now for salvation, so they may know this glorious God for themselves.
