Nursing a viper!
(J. R. Miller, "Devotional Hours with the Bible" 1909)
"Put to death, therefore, whatever belongs to your earthly nature: sexual immorality, impurity, lust, evil desires and greed, which is idolatry. Because of these, the wrath of God is coming. You used to walk in these ways, in the life you once lived." Colossians 3:5-7
A new life in Christ calls for the utter destruction of these evils. It is a shameful list which Paul names. It makes us ashamed to think that such qualities may belong to us—or may nest in our heart! Who would have thought that any these vile things could exist in anyone who wears the human form! Yet many of these ugly things are found in each of us! Our hearts are naturally cages of unclean birds!
What does Paul tell us we should do with these unholy things? He says we are to put them to death. When we find any evil thing in ourselves, we must kill it, for it is not right for it to live. An uncompromising war should be waged against all evil. He who cherishes any impurity in himself—is nursing a viper which will sting him to death by and by!
