And hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation – Acts 17:26.
God sovereignly created one man, Adam. As Adam’s descendants multiplied and formed nations, it was God who designed their course. God has placed within each one of us the yearning to worship, but because of the lust of our flesh (physical desire), lust of the eyes (personal desires), and pride of life (self-interest) we don’t seek Him. We can have fellowship with Him, in fact, every day we depend upon Him for our life and breath whether we know it or not.
We originated from one man, Adam, thus giving us the same blood that was in Adam. Although there are many nations that descended from Adam, they all were made with one blood. We also were created to serve one God; this is the reason why after the flood, and Israel and his children were down in Egypt, God instructed them when they would be delivered from Pharaoh and Egypt not to serve the gods of the surrounding nations (And I will set thy bounds [boundaries] from the Red Sea even unto the sea of the Philistines and from the desert unto the river: for I will deliver the inhabitants of the land into your hands; and thou shalt drive them out before thee. Thou shalt make no covenant [treaty] with them, nor with their gods. They shall not dwell in thy land, lest they make thee sin against me: for it thou serve their gods, it will surely be a snare unto thee – Exodus 23:31-33). Although the Philistine’s were created with the same blood as Adam and was created by the same God as Adam, they didn’t serve the same God. Israel served and worshiped God, and the Philistine’s served the god Dagon, Ashtoreth and Beelzebub.
Different nations served different gods although they were created by the same God, and this is the reason why they were instructed not to serve the gods of the other nations. The instructions hasn’t changed. As professing Christians, we can’t serve the god of this world neither the things he has to offer. Just as the nations set up their own god, so have the people of today chosen who they will serve (Howbeit every nation made gods of their own, and put them in the houses of the high places which the Samaritans had made, every nation in their cities where they dwelt – 2nd Kings 17:29). There is no other way to get to God or His kingdom, but through obedience to the written Word of God, this is why it is so important to read the Word of God, to know the Word of God. (For the time is come that judgment must begin at the house of God: and if it first begin at us, what shall the end be of them that obey not the gospel of God – 1st Peter 4:17).
