Ezk 17:22-23, 1 Cor 1:21
In the Old Testament, world evangelization was prophesied. (Ezk 17:22-23)
Ezk 17:22 Thus saith the Lord God; I will also take of the highest branch of the high cedar, and will set it; I will crop off from the top of his young twigs a tender one, and will plant it upon an high mountain and eminent: 23 In the mountain of the height of Israel will I plant it: and it shall bring forth boughs, and bear fruit, and be a goodly cedar: and under it shall dwell all fowl of every wing; in the shadow of the branches thereof shall they dwell.
Jesus said that the kingdom of God is like the leaven of the flour. Evangelism will make everything swell like leaven. In other words, world evangelization will take place through evangelism. (Lk 13:18-21, 1 Cor 1:21)
Lk 13:18 Then said he, Unto what is the kingdom of God like? and whereunto shall I resemble it? 19 It is like a grain of mustard seed, which a man took, and cast into his garden; and it grew, and waxed a great tree; and the fowls of the air lodged in the branches of it. 20 And again he said, Whereunto shall I liken the kingdom of God? 21 It is like leaven, which a woman took and hid in three measures of meal, till the whole was leavened.
1 Cor 1:21 For after that in the wisdom of God the world by wisdom knew not God, it pleased God by the foolishness of preaching to save them that believe.
