In the Bible, faith is not merely a belief, it is a relationship. It is not how we respond to a proposition; it is how we respond to a person. That person is God — Father, Son and Holy Spirit.
The author of Hebrews says, “But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him” (Hebrews 11:6). Notice, the word, “comes.”
It is not enough to believe that God is. The devil believes in God. As James says, “You believe that there is one God. You do well. Even the demons believe — and tremble!” (James 2:19). The demons have a belief about God, but they have no faith in Him.
Faith is not merely believing that God is. Many people believe that but have no faith. Faith is coming to Him. It is in coming to God that we move from a proposition to a person, from a belief to faith, and enter into a relationship with God.
And that makes all the difference.
