When Jesus began His public ministry, the message was simple, "Repent, for the kingdom of heaven is at hand." (Matthew 4:17) God's message has never changed. In Hosea, 10:12, God says to the hard-hearted and unfaithful nation of Israel, "Sow for yourselves righteousness; reap steadfast love; break up your fallow ground, for it is time to seek the LORD, that he may come and rain righteousness upon you."
To repent means to turn, to change, we have to break up the things that are keeping us separated from God and be open to change. It's time for a new season of growth away from the pale, unfruitful, uselessness of being fallow. It's time to be the new creation God has called us to be and allow His righteousness to rain down upon us!
