John 14:11
Believe me that I am in the Father and the Father is in me; or else believe me because of the works themselves — Jesus offers two grounds for faith: the mystical reality of mutual indwelling, and the empirical evidence of redemptive works (healings, resurrections, casting out of demons) that cannot be explained except through divine agency. Neither ground is merely rational; both require a leap of faith. Yet the works provide a kind of rational foothold for faith—they demonstrate that something transcendent is at work, that God's power flows through Jesus into the world.
