The truth is, we all of us know enough of him to love him more than we do, to delight in him and serve him, believe him, obey him, put our trust in him, above all that we have hitherto attained. Our darkness and weakness is no plea for our negligence and disobedience. Who is it that hath walked up to the knowledge that he hath had of the perfections, excellencies, and will of God? God’s end in giving us any knowledge of himself here is that we may “glorify him as God;” that is, love him, serve him, believe and obey him,—give him all the honour and glory that is due from poor sinful creatures to a sin-pardoning God and Creator. We must all acknowledge that we were never thoroughly transformed into the image of that knowledge which we have had. And had we used our talents well, we might have been trusted with more.
