Mark 1:14

Here is, I. A general account of Christ's preaching in Galilee. John gives an account of his preaching in Judea, before this (ch. 2 and 3), which the other evangelists had omitted, who chiefly relate what occurred in Galilee, because that was least known at Jerusalem. Observe, 1. When Jesus began to preach in Galilee; After that John was put in prison. When he had finished his testimony, then Jesus began his. Note, The silencing of Christ's ministers shall not be the suppressing of Christ's gospel; if some be laid aside, others shall be raised up, perhaps mightier than they, to carry on the same work. 2. What he preached; The gospel of the kingdom of God. Christ came to set up the kingdom of God among men, that they might be brought into subjection to it, and might obtain salvation in it; and he set it up by the preaching of his gospel, and a power going along with it. Observe, (1.) The great truths Christ preached; The time is fulfilled, and the kingdom of God is at hand. This refers to the Old Testament, in which the kingdom of the Messiah was promised, and the time fixed for the introducing of it.
