"For my part, this is my covenant with you. You be the father of many nations ... I will make it extremely proliferators "... Gn.17.4.6 ª. It would be the Lord’s covenant, but would be part of Abraham: "For his part," God said to Abraham, "keep my covenant with you and your descendants. This is my covenant with you and your descendants, a covenant that must be saved: All the male among you shall be circumcised in the flesh. Will they have to mark that this is the sign of the covenant between me and you. " Gn.17.9-11. Every promise is conditional, God does his thing and expect us to do ours, without which there will be the fulfillment of promise: the party of Abraham should mark the people who would serve as the sign of the covenant between God and all that were marked including Abraham. The Lord wants to give us a great multitude of lives, many generations even nations, often this occurs we look the wrong way, we create an expectation that it will suddenly come through our doors a crowd of children, more children are raised and so there must be relationships between people, it is clear that in times of revival inexplicably crowds rush into the arms of God as if the world were to end right then, but time is a craft work done with caution, determination, excellence and tirelessly, so that the brand promise is left in the people that God Himself will send us on our day to day every worship service finally anytime or anywhere it is important to know that the responsibility of disciplic until they are consolidated is ours, while that of God is to make us fertile.
