11 And you shall circumcise the flesh of your foreskin, that it may be for a sign of the covenant between me and you. 12 An infant of eight days old shall be circumcised among you, every man child in your generations: he that is born in the house, as well as the bought servant shall be circumcised, and whosoever is not of your stock: 13 And my covenant shall be in your flesh for a perpetual covenant. 14 The male, whose flesh of his foreskin shall not be circumcised, that soul shall be destroyed out of his people: because he hath broken my covenant. 15 God said also to Abraham: Sarai thy wife thou shalt not call Sarai, but Sara.
16 And I will bless her, and of her I will give thee a son, whom I will bless, and he shall become nations, and kings of people shall spring from him. 17 Abraham fell upon his face, and laughed, saying in his heart: Shall a son, thinkest thou, be born to him that is a hundred years old? and shall Sara that is ninety years old bring forth? 18 And he said to God: O that Ismael may live before thee. 19 And God said to Abraham: Sara thy wife shall bear thee a son, and thou shalt call his name Isaac, and I will establish my covenant with him for a perpetual covenant, and with his seed after him. 20 And as for Ismael I have also heard thee. Behold, I will bless him, and increase, and multiply him exceedingly: he shall beget twelve chiefs, and I will make him a great nation.
Lets place ourselves where Abraham is at the moment he is told his long standing wife will bore him a child after all these many years. Our reaction might be the same. How would it be possible at such an age. Even back then they lived longer but to Abraham it was old. For us it is the end of our lives or close to it. I can't help but notice the fact that God made the impossible happen. In spite of Abraham and Sarah taking care of business themselves by using other means of begetting children for Abram, God chose to forgive and to bless them. He gave us a miracle to read about. The possibility of the impossible. God takes situations and turns them around and makes them possible. Don't we at times when faced with the impossible scoff at our faith and the results like Abraham did. Hard to believe that God could do what he just said. Or for us harder to believe we could be chosen out many to be given his divine presence. It's impossible! It's unlikely! You got to be kidding why that person type of thinking. We snicker, we laugh, we think all sorts of things but the possibility of it being God's Will for us. Just look at the many people who miraculously when faced with the impossible survive illness, or death. We have read of many cases of trapped people and the impossibilty of rescuing them and there too we find the possible. How many times we overlook the possiblity that God wants the best for us and we push him away because we see how impossible it is for him to exist in our lives. With that too he shows us how truly real he is in the impossible moments of our lives when it all becomes possible.
