Think about what you just said there. You basically claiming that the other 5 billion had the light of Christ manifested to them on the level of Jesus and his apostles walking among them. But are rejecting him. That is not the way it works my friend. The point is 100,000 people a day have been accepting Christ in the last decade. There has never been anything like that happen in the world before. They are not rejecting him. they are just hearing him for the first time. The world does not revolve around you. Sorry to break that to you.
Psalm 67: 1 God be merciful to us, and bless us; and cause his face to shine on us; Selah. 2 That your way may be known on earth, your saving health among all nations. 3 Let the people praise you, O God; let all the people praise you. 4 O let the nations be glad and sing for joy: for you shall judge the people righteously, and govern the nations on earth. Selah. 5 Let the people praise you, O God; let all the people praise you. 6 Then shall the earth yield her increase; and God, even our own God, shall bless us. 7 God shall bless us; and all the ends of the earth shall fear him.
Psalm 82: 8 Arise, O God, judge the earth: for you shall inherit all nations.
Psalm 86: 9 All nations whom you have made shall come and worship before you, O Lord; and shall glorify your name.
Isaiah 2:2 And it shall come to pass in the last days, that the mountain of the LORD's house shall be established in the top of the mountains, and shall be exalted above the hills; and all nations shall flow to it. 3 And many people shall go and say, Come you, and let us go up to the mountain of the LORD, to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths: for out of Zion shall go forth the law, and the word of the LORD from Jerusalem. 4 And he shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruning hooks: nation shall not lift up sword against nation, neither shall they learn war any more.
Isaiah 54:1 Sing, O barren, you that did not bear; break forth into singing, and cry aloud, you that did not travail with child: for more are the children of the desolate than the children of the married wife, said the LORD. 2 Enlarge the place of your tent, and let them stretch forth the curtains of your habitations: spare not, lengthen your cords, and strengthen your stakes; 3 For you shall break forth on the right hand and on the left; and your descendants shall inherit the Gentiles, and make the desolate cities to be inhabited. 4 Fear not; for you shall not be ashamed: neither be you confounded; for you shall not be put to shame: for you shall forget the shame of your youth, and shall not remember the reproach of your widowhood any more. 5 For your Maker is your husband; the LORD of hosts is his name; and your Redeemer the Holy One of Israel; The God of the whole earth shall he be called.
Isaiah 55:3....I will make an everlasting covenant with you, even the sure mercies of David. 4 Behold, I have given him for a witness to the people, a leader and commander to the people. 5 Behold, you shall call a nation that you know not, and nations that knew not you shall run to you because of the LORD your God, and for the Holy One of Israel; for he has glorified you. .....10 For as the rain comes down, and the snow from heaven, and returns not thither, but waters the earth, and makes it bring forth and bud, that it may give seed to the sower, and bread to the eater: 11 So shall my word be that goes forth out of my mouth: it shall not return to me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it. 12 For you shall go out with joy, and be led forth with peace: the mountains and the hills shall break forth before you into singing, and all the trees of the field shall clap their hands. (The mountains and trees are typical Biblical illustrations of the nations.)13 Instead of the thorn shall come up the fir tree, and instead of the brier shall come up the myrtle tree: and it shall be to the LORD for a name, for an everlasting sign that shall not be cut off.
