Repent and believe the good news.
From that time on, Jesus began to preach and say, “Repent, for the kingdom of heaven is at hand.” Matthew 4:17
“This is the time of fulfillment. The kingdom of God is at hand. Repent, and believe in the gospel.” Mark 1:15
The Kingdom of God has come to earth through Jesus. His work in restoring creation is now in process. He has begun the process of seeing His work done again on earth as it is in heaven. He commands us to voluntarily change our minds and our lives to allegiance to Him and alignment with His reign. This is good news. He will right all wrongs. He will fix all that is broken. He gives us the opportunity to join Him in ruling the renewed world forever. Our only alternative is to continue in our brokenness and, in the end, be forced to acknowledge His rule and face punishment as His enemies.
