Put to death therefore what is earthly in you … (Colossians 3:5 ESV)
Beyond all the other must-do items on the schedule today, the child of God is commanded to show no mercy in putting to death his sinful acts, words and thoughts. He cannot shelter, pamper, indulge, coddle or let live even the slightest thought that is raised against the person and authority of Jesus Christ. Through the indwelling presence of the Holy Spirit, the believer is enabled to live in godliness and pursue holiness. He is now called to carry out that mission for his own safety and the glory of Christ.
As John Owen put it: "Be killing sin or it will be killing you."
