Mark 1:15

As if he were to say: To this day the Mosaic law has been in full force, but henceforth the evangelical law shall be preached; which law is not undeservedly compared to the kingdom of God. (Theophylactus) — Repent, therefore, says our Saviour, and believe the gospel; for if you believe not, you shall not understand; repent, therefore, and believe. What advantage is it to believe with good works? the merit of good works will not bring us to faith, but faith is the beginning of good works. (St. Jerome)

I. His baptism, which was his first public appearance, after he had long lived obscurely in Nazareth. O how much hidden worth is there, which in this world is either lost in the dust of contempt and cannot be known, or wrapped up in the veil of humility and will not be known! But sooner or later it shall be known, as Christ's was.

Verses 14-22 Jesus began to preach in Galilee, after that John was put in prison. If some be laid aside, others shall be raised up, to carry on the same work. Observe the great truths Christ preached. By repentance we give glory to our Creator whom we have offended; by faith we give glory to our Redeemer who came to save us from our sins. Christ has joined these two together, and let no man think to put them asunder. Christ puts honour upon those who, though mean in this world, are diligent in their business and kind to one another. Industry and unity are good and pleasant, and the Lord Jesus commands a blessing on them. Those whom Christ calls, must leave all to follow him; and by his grace he makes them willing to do so. Not that we must needs go out of the world, but we must sit loose to the world; forsake every thing that is against our duty to Christ, and that cannot be kept without hurt to our souls. Jesus strictly kept the sabbath day, by applying himself unto, and abounding in the sabbath work, in order to which the sabbath rest was appointed. There is much in the doctrine of Christ that is astonishing; and the more we hear it, the more cause we see to admire it.
