"Jesus went into Galilee, proclaiming the good news of God.
“The time has come,” he said.
“The kingdom of God has come near.
Repent and believe the good news!”
"Through Adam's rebellion, a rival regime establishes a beachhead in God's world. While God is the rightful King, the fallen sons of Adam (us) refuse to swear allegiance to his rule or follow his commands. Yet in his grace, God commits himself to reclaim lost allegiance and to deliver man from the awful regime of sin and death. "

When Jesus came proclaiming the kingdom of God, he was proclaiming the good news of this new regime. In God's gracious initiative, the Son came to earth to redeem his creation that had been enslaved by the regime of sin. The Gospel is that the kingdom is here. God has come to restore his regime. He invites us to turn from our allegiance to sin, and turn to the One and True God, who has ushered in the new kingdom through Jesus.
