Genesis chapter 17

1 When Abram was ninety-nine years old, the Lord appeared to him and said, I am God Almighty; walk before me and be blameless.
2 I will confirm my covenant between me and you and will greatly increase your numbers.


Here, God confirms the covenant between him and Abraham, telling him that he and Sarah will have a son, Isaac, who is the child of the promise, the covenant. Whilst Ishmael, the child of the flesh, will be blessed also, it is through Isaac that Abraham will be the father of many nations.
This is not the first time that God has talked about the covenant with Abraham. It is mentioned in chapter 12 and chapter 15, but here, it is all about to take place, with Isaac's birth foretold sometime in the next year. This is something that Abraham at the age of 100, with Sarah now 90, thought impossible. Yet nothing is impossible for God and I am reminded of God telling Moses "The Lord answered Moses, "Is the Lord's arm too short? You will now see whether or not what I say will come true for you." (Numbers 11:23).

All these chapters here are reminding me about having faith, about trusting in God, no matter what. Trust and believe, for the arm of the Lord is not too short and for Him, nothing is impossible.
