David Fry explains in this video that Abraham gave us a positive example of biblical fatherhood. We have many situations of how involved he was with the Lord but also with his son and his nephew, Lot. Even though he wasn't perfect, he strived to walk according to what God commanded.

Proverbs 20:7 (NKJV) - "The righteous man walks in his integrity; his children are blessed after him."

So in terms of Abraham and what he did right as a father, what we have in Abraham is probably the best example of biblical fatherhood in the scriptures along with Job, with one or two exceptions from his life of course, but we have many episodes that show how involved he was and not only with the Lord but then as that translated into his fatherhood. So beginning with this call in Genesis 12, this is what propelled him really into his fatherhood and to think multi-generationally. So he would have this call from God in Genesis 12. He would rescue Lot. He would have the covenant of circumcision.

He would then take the promise from God that his wife Sarah would bear a son, and then he would take Isaac to Mount Moriah. So we have all of these episodes of Abraham in which he was very faithful. And when Isaac, as a premier event that would show how what his trust in God would be was when he took Isaac to Mount Moriah and was ready to sacrifice him knowing that God would even raise him from the dead, and that he would return to those servants back at the base of the hill, after worshiping God with his son. And so he had a tremendous amount of trust. So his son would see in his dad this calling of Genesis 12 that would propel him.

Isaac knew that story of his father and he would understand that this was from his father's soul that they have a generational line that would ultimately bring about numerous descendants and even the Messiah who would be to come.
