says faith is an assurance of what we ask for—things hoped for. The word “assurance” comes from the Greek word hupostasis. This was also the Greek word for a title deed. Biblical faith is knowing with certainty deep in our hearts that we have what we ask God for, just as surely as a title deed proves that we own a piece of property.
The same verse in the King James Version tells us that faith is our evidence of things we cannot see. “Evidence” is from the Greek word elegchos, which literally means the proof of the charges in a legal court case that results in a conviction. The word was used in a court of law for evidence significant enough to prove a case and result in a conviction. In other words, our faith in God’s Word or His promises is all the evidence we need to validate our conviction.
