Hebrews 11:1, “Now faith is the substance of things hoped for, the evidence of things not seen.”
Each of us has a “measure of faith”, how big that measure is has been determined by God. He gives our faith to us, whether we use it for His purposes or call it “hope” and use it for our own purpose, it is part of our salvation process. Because without faith we can’t please God and without faith, we won’t recognize our need for salvation, so we have to have it in order to be saved in the first place.
Abram believed in God and it was counted to him for righteousness. Faith and belief go together because if you don’t have one you won’t have the other. It takes faith to believe the promises of the Bible and to believe in Jesus Christ as your Savior. Some say that the Bible can’t be true but it is. It is the most truthful book in our world because all of the prophecies about Jesus were fulfilled in Jesus the Christ. All of the prophecies about the Jewish people have come true except their having peace in their land and that will come true after the Tribulation.
