In Mark 1, as Jesus begins his ministry on earth, he says in verse 15 “Repent and believe in the Gospel”. The word “repent” means to turn around one’s behavior or way of thinking. Repenting from what, one might ask? Some say repent from sin. But repenting from sin doesn’t make you a Christian. We’ve already established the fact that we do not become Christians by doing something. We should repent rather from our sense of self-justification and self-righteousness. Repent from believing that we can justify access to God and heaven by our own works and our own self-righteousness, and rather believe that God is the one who justifies us through the work of his Son, Jesus. We need only believe. Paul says in Romans 4:5 that it is God who justifies the ungodly. This is such good news. God does the heavy lifting. We need only to have faith in this and believe!
