Faith is not some whimsical muse, some will-o’-the-whisp. It doesn’t flit here and there void of our volition - any more than love is a feeling that comes and goes.
Sometimes faith is unconscious. Ofttimes it is deliberate, intentional. We must have the ability to exercise or employ faith, else why would we be expected to live by it? Why would it be impossible to please Our Heavenly Father apart from it?
God designed faith as our means of apprehending His exhilarating and transformative promises - as the one only faculty by which we may partake of His Divine nature.
