“A nail is driven out by another nail; habit is overcome by habit.” Erasmus of Rotterdam, contemporary of Martin Luther.
Nail marks in His hands…”unless I put my finger where the nails were … I will not believe.”
A nail-habit of unbelief can only be driven out by the iron-sharper nail of perfect love. It takes practice, believing does, to hit the nail on the head, but practice makes perfect, so they say.
So we practice hammering in nails of belief to pound out nails of unbelief; and in the doing, we learn the secret of Perfect Love: the love of a carpenter’s son and Savior of the world; a love that drives out fear, the quintessence of all unbelief.
