From Bible school I remember that Joshua 21:45 is the key verse of the book of Joshua.

There it says:

“Not one of all the LORD’S good promises to the house of Israel failed; every one was fulfilled.”

I am making an effort to remember PROMISES from the Bible. I think I can say the following without looking at them in the Bible:

Charles Haddon Spurgeon says: “NO PROMISE  IS FOR PRIVATE INTERPRETATION. WHATEVER GOD HAS SAID TO ANY ONE SAINT, HE HAS SAID TO ALL.”
