Matthew shows disciples of Jesus what it means to catch people by the Kingdom of God.
Matthew shows us that the beginning of Jesus' ministry fulfills an ancient promise to the lands of Galilee for light and blessing from God. This reminds disciples of the focus of our service in the Lord.
In Matthew 4:1-11 Jesus is tested by Satan as to whether Jesus--unlike Israel before him--would live up to God's acclaim of Jesus as "My son, in whom I am well pleased."

Matthew's account of Jesus' baptism by John the Baptist raises the question of why Jesus was baptized. In answering this question, we find that Jesus' baptism models the form of entering and living in the Kingdom of Heaven. For those who faithfully accept the calling to righteousness, Heaven responds with access, anointing, and acclamation for attaining still more righteousness, to the glory of God.
