Chapter 1:9-13 The Baptism of Christ

1:9 And it came to pass in those days, that Jesus came from Nazareth of Galilee, and was baptized of John in Jordan.

See how honorably God owned Him, when He submitted to John's baptism.
1:10 And straightway coming up out of the water, He saw the heavens opened, and the Spirit like a dove descending upon Him:

He saw the heavens opened; thus he was owned to be the Lord from heaven, and had a glimpse of the glory and joy that were set before Him. 

He saw the Spirit like a dove descending upon Him. Note, Then we may see heaven opened to us, when we perceive the Spirit descending and working upon us. God's good work in us is the surest evidence of his good will towards us, and his preparations for us.
1:11 And there came a voice from heaven, saying, Thou art My beloved Son, in whom I am well pleased.

He heard a voice which was intended for His encouragement to proceed in His undertaking, and therefore it is here expressed as directed to Him, Thou art My beloved Son.
1:12 And immediately the Spirit driveth Him into the wilderness.

The Spirit driveth Him - Εκβαλλει, putteth him forth.
1:13 And He was there in the wilderness forty days, tempted of Satan; and was with the wild beasts; and the angels ministered unto Him.

With the wild beasts - This is a curious circumstance, which is mentioned by none of the other evangelists; and seems to intimate that he was in the most remote, unfrequented, and savage part of the desert; which, together with the diabolic influence, tended to render the whole scene the more horrid. Mark observes this circumstance of his being in the wilderness—that he was with the wild beasts. 

It was an instance of His Father's care of Him, 

that He was preserved from being torn in pieces by the wild beasts, which encouraged Him the more that His Father would provide for Him when He was hungry.
