In the early Church there was nothing of the uncertainty which we find among Christians now. They knew what they were, and it was on the authenticated facts concerning Christ that they rested this certainty. No one then thought of saying, I believe, but I am not sure whether I am born of God; for they took for granted that whosoever believeth that Jesus is the Christ is born of God. They did not analyze their own faith to ascertain how far it was of the right quantity and quality. They never thought of themselves at all, but only of Him who, though rich, for their sakes had become poor.
Horatius Bonar (1809 – 1889)
