Genesis 21:1-21

What’s Best for Us


Sometimes in the Christian life we become distressed about unfortunate circumstances. From our point of view we cannot understand why this is happening to me? As we see from our text God commands Abraham not to be distressed – v.12. God commands his servant to do specific things but does not usually tell us why. The why of doing is not always clear at the outset, but we discover later that God’s way was best for us.

We are urged by the apostle to present our bodies a living and holy sacrifice. It becomes our spiritual service of worship. “And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what the will of God is, that which is good and acceptable and perfect.” (Romans 12:1-2)
