The mould of Christian doctrine.
The Christian, in remembering what he was, deepens his impression of Divine grace, to which he owes it that the. change has been effected in which he now rejoices. St. Paul took a peculiar satisfaction in reviewing his own experience, and acknowledging his indebtedness to that Divine grace which had fashioned his character anew. And if the Christian will consider the state in which he would have been apart from the supernatural doctrine and influences of Christianity, he will see reason for gratitude in the provision made for the transformation and renewal of his character. In this verse the change is attributed, instrumentally, to the power of Christian doctrine, which is, as it were, a pattern by which he is reconstructed, or a mould into which the metal of his nature has been cast, in order to its taking a new and divinely ordered shape and form.
I. THE CHRISTIAN DOCTRINE IS AS A MOULD PREPARED IN ORDER TO GIVE A NEW SHAPE AND FORM TO THE HUMAN CHARACTER. When iron is "cast," it is run, in a liquid state, into a shape or mould of earth or sand of the desired form; and thus the artificer produces a bolt or a cannon. Thus, in the intellectual and spiritual realm, ideas govern men; and the character and life are largely owing to the thoughts which are familiar and congenial And Christian doctrine is not an end, but a means; the righteousness and love of God, revealed in Christ, having power to reconstruct the character and to renew the life. The doctrine is alive with the power of the Holy Spirit of God.
II. THE CHRISTIAN DISCIPLE IS CAST INTO THIS SPIRITUAL MOULD, THAT HE MAY TAKE ITS NEW SHAPE AND FORM. The old elements of human nature, old errors and old sins, are dissolved and melted down when brought into contact with the gospel of Jesus Christ. Old things pass away, in order that all things may become new. We may fancy that the doctrine is delivered unto us, to do what we like with it; but the reverse is the case. We are delivered unto it, in order that it may do its work upon us. So it is with the Christian education of the young, and with the evangelization of the heathen. The mould of Christian doctrine imparts to him who is brought into living contact with it a new motive to holiness, in the redeeming and sacrificial love of the Saviour; a new rule of holiness, in his law and life; and new help towards holiness, in the provision of the Spirit's help and grace. A moral transfiguration is effected, as the natural result of intelligent acceptance and voluntary allegiance. For if faith is the soul of obedience, obedience is the body of faith. There is no change so wonderful and so admirable as that which is wrought in human character by the moulding power of Christian doctrine.
