If the Lord has said it; He will also do it. All His Words are true and infallible. We not see it therefore we scared, we are afraid, but He said as far as you can see. Not only to you but also to your generation to come. (Gen 13:14-15)

That is why it is important that our fathers are strong in the place of prayer because they usually receive generational covenant for their generations to come. It is good that they walk blameless before God so that the Lord will bless them and honour them and their seeds will be blessed of the Lord (Ps 112:2).
