1. God promised world evangelization (Jos 1:2-5)
    Mt 20:18-20, Mk 16:15-16, Acts 1:8

In the Old Testament, God told Joshua that he would completely occupy the land of Canaan. (Joshua 1:2-5)

Joshua 1:2 Moses my servant is dead; now therefore arise, go over this Jordan, thou, and all this people, unto the land which I do give to them, even to the children of Israel.
3 Every place that the sole of your foot shall tread upon, that have I given unto you, as I said unto Moses.
4 From the wilderness and this Lebanon even unto the great river, the river Euphrates, all the land of the Hittites, and unto the great sea toward the going down of the sun, shall be your coast.
5 There shall not any man be able to stand before thee all the days of thy life: as I was with Moses, so I will be with thee: I will not fail thee, nor forsake thee.

Jesus commanded us to do world evangelization and promised world evangelization. (Mt 28:18-20, Mark 16:15-16, Acts 1:8)

Mt 28:18 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.
19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen.

Mark 16:15 And he said unto them, Go ye into all the world, and preach the gospel to every creature.
16 He that believeth and is baptized shall be saved; but he that believeth not shall be damned.

Acts 1:8 But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
