21 But my covenant I will establish with Isaac, whom Sara shall bring forth to thee at this time in the next year. 22 And when he had left off speaking with him, God went up from Abraham. 23 And Abraham took Ismael his son, and all that were born in his house: and all whom he had bought, every male among the men of his house: and he circumcised the flesh of their foreskin forthwith the very same day, as God had commanded him. 24 Abraham was ninety and nine years old, when he circumcised the flesh of his foreskin. 25 And Ismael his son was full thirteen years old at the time of his circumcision.
26 The selfsame day was Abraham circumcised and Ismael his son. 27 And all the men of his house, as well they that were born in his house, as the bought servants and strangers were circumcised with him
We have to admit that Abraham even in his great age did what was asked of him. Also of the other members as well. That alone was an undertaking of itself. It was also the fact that Abraham did what God asked of him. He did his will! God bless him for that. We think about the many things that God asks of us, and very many of them are not hard at all. It's us who deem what is hard to do and what is not. Since Abraham didn't do as asked one time he was given this one time to show his faithfulness. For us, all God asks of us is to follow his will just like he did with Abraham a few times. Only difference between then and now is our penchant to follow the world and our own will, with the mind set to forget about God and his covenant to us. If doing God's will was important in our lives we would be filling the Churches on Sundays and observing his day. We would live morally correct lives, but most of all we would love him above all else. What is the excess in our lives that we need to circumcise from.
