3:1-6 Christ is to be considered as the Apostle of our profession, the Messenger sent by God to men, the great Revealer of that faith which we profess to hold, and of that hope which we profess to have. As Christ, the Messiah, anointed for the office both of Apostle and High Priest. As Jesus, our Saviour, our Healer, the great Physician of souls. Consider him thus. Consider what he is in himself, what he is to us, and what he will be to us hereafter and for ever. Close and serious thoughts of Christ bring us to know more of him. The Jews had a high opinion of the faithfulness of Moses, yet his faithfulness was but a type of Christ's. Christ was the Master of this house, of his church, his people, as well as their Maker. Moses was a faithful servant; Christ, as the eternal Son of God, is rightful Owner and Sovereign Ruler of the Church. There must not only be setting out well in the ways of Christ, but stedfastness and perseverance therein to the end. Every meditation on his person and his salvation, will suggest more wisdom, new motives to love, confidence, and obedience.
