Hebrews 11:20

There are things Isaac could have differently as a father that might have had an impact on his sons. He could have lay there on his death bed torturing himself by listing all the things he could have done differently but rather than focussing on his own failures he focussed on God’s promises. He lived by faith. He died in faith.

This is the life we’re called to. This is what we see in the life of Jesus.
