Do not be Afraid: Genesis 26:24
What God had said to Abraham (15:1), he says to his son Isaac. The life of faith involves fearing God rather than people, recognising that he is powerful enough to overcome every obstacle to the fulfilment of his promises.
The Sign in the Flesh: Genesis 17:13
The sign of the Abrahamic Covenant, the sign of circumcision, was “in your flesh” (Gen. 17:13), where it simultaneously marked God’s extraordinary promise and Abraham’s complete impotency.
“Blessed is the one … whose delight is in the law of the Lord, and who meditates on his law day and night. That person is like a tree planted by streams of water that yields its fruit in season.”
— Psalm 1:1-3
