Biblical faith involves knowledge.
Faith is dependent upon what can be known about God. In fact, the New Testament says that faith involves us coming to know God Himself. In John 17:3, Jesus says, “This is eternal life, that they know you, the only true God, and Jesus Christ whom you have sent.”
How can you know God? In the person of His Son, the Lord Jesus Christ! Speaking of Jesus, John 1:18 says, “No one has ever seen God; the only God, who is at the Father’s side, he has made him known.” That’s why it is so important to consider the claims that Jesus made: it is in knowing Him that we know God. And it is this knowledge of God that gives us the basis for our faith.
