Matthew 17:20 – “And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.”
Belief says, “You can do it, because I’ve seen you do it countless times before but in order to do this particular one, I’ll need proof and enough assurance that you are able.”
Faith says, “You are capable of doing ANYTHING, even this particular one, even though I’ve never seen you do such before.”
Abraham had faith, The Centurion had faith (Matt 8:1-10). Jesus was faith personified while on earth. Thomas and most of the disciples then had belief, especially the ones that left Jesus when they couldn’t fathom what He was saying in John 6:53-66.
“Belief” wait for evidences before acting. “Faith” doesn’t need evidences; it acts without one.
