What Is Earthly
There is a way that we must hate the things of earth so that we can also love the things of earth in a different way. In order to change the world we must not be slaves to the world; we cannot worship the world and offer that to God. That’s idolatry, and the Lord is jealous for His own glory.
So let us take very seriously our responsibility to hate the things of earth as God defines the things of earth. We must take extreme measures as individuals and as a church to deal with “what is earthly” in us.
In Colossians 3:5-11 Paul gives three commands: 1) put to death, 2) put away, and 3) do not lie.
We must “put to death what is earthly” in us, and that includes any sort of sexual sin, whether in our hearts or with our parts. We must kill greed, which is the functional equivalent of idolatry, sacrificing ourselves for the pleasures of money rather than for the pleasures of God. But “on account of these the wrath of God is coming.” Therefore, mortify sin for sake of honoring the marriage bed on earth. Put sin to death in order to be generous with wealth in this world.
We must also “put them all away: anger, wrath, malice, slander, and obscene talk.” This verb could be translated “take off,” as if we were wearing soiled and stained clothes. The contrast comes in the next paragraph with “put on” the character of Christ. Don’t put on rage and bitterness, those are earthly things. Instead, put on kindness and patience here and now. Put on thankful diligence in the work God gives.
And then “do not lie to one another.” We are people of the truth because we are not what we used to be.
Our new selves are “being renewed in knowledge after the image of its creator.” Creation is not the problem, our sin is the problem, and we must be ruthless in repenting from it or it will ruin us. As John Owen wrote, “Do you mortify; do you make it your daily work; be always at it whilst you live; cease not a day from this work; be killing sin or it will be killing you.”
