It’s striking, the number of Bible passages that warn God’s people of the danger they face if they continue to indulge the sinful nature. When I was a child, we dismissed the warnings by saying they were addressed to pseudo-Christians who were never really saved in the first place. Not so.
Dear brothers and sisters, listen closely to what God has to say to his people through his Word. The days are evil. Your witness is at stake. The Lord is blasphemed when we live down to the world’s expectations. Now is the time to get rid of immorality and impurity. Now is the time to get rid of anger and slander. Strip away anything that remains of your old life, and put on Christ. “Be renewed as you learn to know your Creator and become like him.”
Colossians 3:1-10 — Since you have been raised to new life with Christ, set your sights on the realities of heaven, where Christ sits in the place of honor at God’s right hand. Think about the things of heaven, not the things of earth. For you died to this life, and your real life is hidden with Christ in God. And when Christ, who is your life, is revealed to the whole world, you will share in all his glory.
So put to death the sinful, earthly things lurking within you. Have nothing to do with sexual immorality, impurity, lust, and evil desires. Don’t be greedy, for a greedy person is an idolater, worshiping the things of this world. Because of these sins, the anger of God is coming.
You used to do these things when your life was still part of this world. But now is the time to get rid of anger, rage, malicious behavior, slander, and dirty language. Don’t lie to each other, for you have stripped off your old sinful nature and all its wicked deeds. Put on your new nature, and be renewed as you learn to know your Creator and become like him. (NLT)
