The Bible is given to us to change our thinking so we can begin to think like God does. As far as God was concerned, it was already a fact. He knew He was able to bring it to pass. God does not bring things to pass when we refuse to cooperate with Him. When we refuse to believe His Word and obey Him, God's will in our lives is hindered.
Several scriptures prove that.
It also says God was not able to bless Israel as He wished to. So we see that they could not enter in because of unbelief. Then your peace would have been like a river, and your righteousness like the waves of the sea. We must cooperate with God. The Word Judges Us Many think they should judge God's Word to determine if it is correct.
