Gen 26:3-4, Mt 28:18-20
God told Abraham that Abraham's descendants would multiply and that all peoples under the world would be blessed through Abraham's descendant, Christ. (Gen. 26:3-4)
Gen. 26:3 Sojourn in this land, and I will be with thee, and will bless thee; for unto thee, and unto thy seed, I will give all these countries, and I will perform the oath which I sware unto Abraham thy father; 4 And I will make thy seed to multiply as the stars of heaven, and will give unto thy seed all these countries; and in thy seed shall all the nations of the earth be blessed;
In the Old Testament, the 80-year-old Caleb asked Joshua to ask for the mountain of Anak because if God were with him he could drive out the mountain of Anak. (Joshua 14:10-12)
Joshua 14:10 And now, behold, the Lord hath kept me alive, as he said, these forty and five years, even since the Lord spake this word unto Moses, while the children of Israel wandered in the wilderness: and now, lo, I am this day fourscore and five years old.
11 As yet I am as strong this day as I was in the day that Moses sent me: as my strength was then, even so is my strength now, for war, both to go out, and to come in.
12 Now therefore give me this mountain, whereof the Lord spake in that day; for thou heardest in that day how the Anakims were there, and that the cities were great and fenced: if so be the Lord will be with me, then I shall be able to drive them out, as the Lord said.
Jesus, the Christ, has commanded us to evangelize the world. Because Jesus is always with us, we can do world evangelization. (Mt 28:18-20)
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.
