In the Gospels the biblical word used for repentance is the Greek word “metanoia” – a radical change of mind, heart, soul and action. It happens when one changes course and turns around to walk in the right direction. Metanoia means a life-changing conversion. That’s what Jesus is calling us to when he says “repent.”
Think of some of the great saints who deeply repented, who truly experienced a metanoia.
St. Paul did a complete about face. He went from persecuting the followers of Christ, to championing their cause and suffering with them.
St. Augustine of Hippo turned from fleeting unmarried sexual pleasure and unsatisfying philosophical pursuits to a totally fulfilling surrender to the will of God. In his famous autobiographical “Confessions” he sums it all up so well: “You [God] have made us for yourself, and our heart is restless until it rests in you.”
When we allow our heart to rest in God, we become a new creation, fully dedicated to advancing his kingdom. But this takes humility, honesty, much prayer and hard work. Not for the faint-hearted.
The respected English writer and theologian G.K. Chesterton wrote, “Christianity has not been tried and found wanting; it has been found difficult and not tried.”
