Seeing Begets Being

The duty of “meditating” much on the glory of the gospel, 2Co_3:18. It is by that we are purified. It is by keeping it constantly before the mind; dwelling on its splendor; thinking of its glorious truths, that we become transformed into the same image, and made like God. If the character is formed by the objects which we contemplate, and with which we are familiar; if we are insensibly moulded in our feelings and principles by that with which we constantly associate, then we should “think” much of the truths of the gospel. We should pray much - for thus we come in contact with God and his truth. We should read the Scripture much. We should commune with the good and the pure. We should make our companions of those who most love the Lord Jesus, and most decidedly bear his image. We should think much of a pure heaven. Thus shall we be moulded, insensibly it may be, but certainly, into the image of a holy God and Saviour, and be prepared for a pure and truly heaven.
Albert Barnes on 2 Cor 3:18
