Charles Haddon Spurgeon said this quote

We are not worthy to unloose the latchets of Jesus' shoes, because, if we do, we begin to say to ourselves, What great folks are we; we have been allowed to loose the latchets of the Lord's sandals. If we do not tell somebody else about it with many an exultation, we at least tell ourselves about it, and feel that we are something after all, and ought to be held in no small repute.
