The Bible tells us that everyone who has believed in Jesus is a person born again, resurrected from the dead, dead to earthly things and alive to eternal things. We do not know how much this is appreciated in our churches, since today there is a great decline in many who claim to be Christians, but the truth is that God has a people, which causes earthly things to die by the power of His strenght.
The apostle Paul wrote to the Colossians:
5 Mortify therefore your members which are upon the earth; fornication, uncleanness, inordinate affection, evil concupiscence, and covetousness, which is idolatry:
6 For which things’ sake the wrath of God cometh on the children of disobedience:
7 In the which ye also walked some time, when ye lived in them.
When the Bible tells us about the “earthly” let us not believe that it refers to everything that is on earth, because if so we could not live in this world. The apostle here is referring to the system of this world, to what the world calls good, but that we ourselves know is bad.
Paul here mentions some of those earthly things: fornication, uncleanness, inordinate affection, evil concupiscence, etc, and the only way for us to make all those things die is to live a full life in the Lord.
Let us remember that once we walked in those things and for us it was normal, but it can no longer be normal, since we have died to sin, therefore we have also died to earthly things, which means that we no longer live according to the system of this world, but according to the model of God.
