1. Even we,ourselves eagerly wait for the world evangelization within ourselves. (Rom 8:23)
    Mt 24:14, Col 3:4, 2 Cor 5:2

Inwardly we too await the redemption of our bodies. It means that we, too, are waiting for world evangelization inwardly. (Rom 8:23, 2 Cor 5:2)

Rom 8:23 And not only they, but ourselves also, which have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, to wit, the redemption of our body.

2 Cor 5:2 For in this we groan, earnestly desiring to be clothed upon with our house which is from heaven:

The end of the world will come only when the world is evangelized, and only then will Christ return. (Mt 24:14,Col 3:4)

Mt 24:14 And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.

Col 3:4 When Christ, who is our life, shall appear, then shall ye also appear with him in glory.
