3:6-10 All whom God calls to any office he finds fit, or makes so. The Lord will cause the sins of the believer to pass away by his sanctifying grace, and will enable him to walk in newness of life. As the promises made to David often pass into promises of the Messiah, so the promises to Joshua look forward to Christ, of whose priesthood Joshua's was a shadow. Whatever trials we pass through, whatever services we perform, our whole dependence must rest on Christ, the Branch of righteousness. He is God's servant, employed in his work, obedient to his will, devoted to his honour and glory. He is the Branch from which all our fruit must be gathered. The eye of his Father was upon him, especially in his sufferings, and when he was buried in the grave, as the foundation-stones are under ground, out of men's sight. But the prophecy rather denotes the attention paid to this precious Corner-stone. All believers, from the beginning, had looked forward to it in the types and predictions. All believers, after Christ's coming, would look to it with faith, hope, and love. Christ shall appear for all his chosen, as the high priest when before the Lord, with the names of all Israel graven in the precious stones of his breastplate. When God gave a remnant to Christ, to be brought through grace to glory, then he engraved this precious stone. By him sin shall be taken away, both the guilt and the dominion of it; he did it in one day, that day in which he suffered and died. What should terrify when sin is taken away? Then nothing can hurt, and we sit down under Christ's shadow with delight, and are sheltered by it. And gospel grace, coming with power, makes men forward to draw others to it.
