"I will maintain my covenant with you and your descendants after you throughout the ages as an everlasting pact, to be your God and the God of your descendants after you." Gn 17:7
When Abraham heard that he would be the father of many nations, he was very much afraid. After all, he was ninety nine years old and could not imagine that God would choose him for so noble a task. I can imagine that for a time at least, he thought he was going mad and that everything God said to him was only a dream. Abraham had been unable to conceive a child with Sarah and now this! How could it be. No doubt Abraham expected that God would lay heavy burdens upon him, and he was not sure he was up to the task.But God's demands are light. Abraham had only to keep the covenant which God make with him in a unilateral way. He didn't have to worry about penalties and punishment. He had only to be circumcised so that there would a sign "in his body" that indicated his acceptance of the living God. God wanted Abraham to know peace and he wants us to be at peace, too.
Today, glory in God's covenants with us.
Have you ever been frightened by God's call?
