"I would like you to respond to this passage from Mark."
[Mark 1:14-15 NKJV] 14 Now after John was put in prison, Jesus came to Galilee, preaching the gospel of the kingdom of God, 15 and saying, "
The time is fulfilled, and the kingdom of God is at hand. Repent, and believe in the gospel."
[Matthew 4:12-17 NKJV] 12 Now when Jesus heard that John had been put in prison, He departed to Galilee. 13 And leaving Nazareth, He came and dwelt in Capernaum, which is by the sea, in the regions of Zebulun and Naphtali, 14 that it might be fulfilled which was spoken by Isaiah the prophet, saying: 15 "The land of Zebulun and the land of Naphtali, [By] the way of the sea, beyond the Jordan, Galilee of the Gentiles: 16 The people who sat in darkness have seen a great light, And upon those who sat in the region and shadow of death Light has dawned." 17 From that time Jesus began to preach and to say, "
Repent, for the kingdom of heaven is at hand."
[Luke 4:14-15 NKJV] 14 Then Jesus returned in the power of the Spirit to Galilee, and news of Him went out through all the surrounding region. 15 And He taught in their synagogues, being glorified by all.
I think it means:
- Jesus went to Galilee
- Jesus warned people to "Repent" (Just as John the Baptist had).
- Jesus warned people that "the kingdom of God is at hand" (Just as John the Baptist had).
- This was the "good news" (gospel) mentioned in Mark 1:15
- Jesus cannot have started his ministry asking people to believe the "Gospel" that "Jesus is God and he has died for their sins and the Father raised him from the dead; now that he has ascended into heaven, those who confess Jesus is Lord and believe God raised him from the dead will be saved and are sealed with the Holy Spirit as a deposit guaranteeing their inheritance" ... so the call to believe the "good news" must be some good news different from the good news that we know today.
