Faith in Christ, not mere belief

Faith in Christ is more than the mere acknowlegment that Jesus is God, for as it says in James even the devils believe. “Thou believest that there is one God; thou doest well: the devils also believe and tremble.” (James 2:19 KJV) The devils tremble because they don’t have faith and so won’t be saved. Love of Christ is what elevates mere belief to saving faith.
