Read: Deuteronomy 28:13
13 The Lord will make you the head (leader) and not the tail (follower); and you will be above only, and you will not be beneath, if you listen and pay attention to the commandments of the Lord your God, which I am commanding you today, to observe them carefully.
12 The Lord will open for you His good treasure house, the heavens, to give rain to your land in its season and to bless all the work of your hand; and you will lend to many nations, but you will not borrow.
9 The Lord will establish you as a people holy [and set apart] to Himself, just as He has sworn to you, if you keep the commandments of the Lord your God and walk [that is, live your life each and every day] in His ways.
So will My word be which goes out of My mouth;
It will not return to Me void (useless, without result),
Without accomplishing what I desire,
And without succeeding in the matter for which I sent it.
What God has done for one he will do for another.. He is not a receptor of persons.
Read Joshua 21:43-45
43 So the Lord gave to Israel all the land he had sworn to give their ancestors, and they took possession of it and settled there. 44 And the Lord gave them rest on every side, just as he had solemnly promised their ancestors. None of their enemies could stand against them, for the Lord helped them conquer all their enemies. 45 Not a single one of all the good promises the Lord had given to the family of Israel was left unfulfilled; everything he had spoken came true.
