It is important that we learn to say “Yes” when “Yes” is the true answer. To all invitations upward to truer, deeper, richer, nobler life we should instantly answer “Yes.” All calls to duty, to holy service, to noble deeds, to heroic battle, we should meet with glad "Yes." While we instantly shut our hearts against all that is impure and unholy, all thoughts that would tarnish or stain or blight, we should open them just as quickly to all thoughts that are pure and true and honest and just and lovely. One of the old Bible answers which we hear so often from the lips of saintly men, when called of God, is, “Here am I.” It meant readiness for instant, unquestioning obedience. We need to get the same answer into our heart’s vocabulary, that when God calls we may always respond with our prompt, ringing “Here am I.”
