Sin is a spiritual sickness we all carry. In this week’s passage from Mark 9:38-50, Jesus has some serious words of caution for us regarding sin. We must do everything in our power to kill it and eliminate it from ourselves. The consequences of not doing that are too costly to risk not heeding Jesus’ command. He calls us to a life of ongoing repentance in order to receive the free gift of grace he willingly died to give to us.
