"And they sang a new song, saying, Thou art worthy to take the book, and to open the seals thereof; for Thou wast slain, and hast redeemed us to God by the blood OUT OF every kindred, and tongue, and people, and nation; and hast made us unto our God kings and priests: and we shall reign on the earth" (Rev. 5: 9-10).
This scripture does not tell us that Christ died, shed His blood, and redeemed everyone in every nation. It clearly states that He was slain and did redeem to God by His blood a people (His church) OUT OF every tongue and people. And when those whom the Father chose in Christ, for whom the Saviour died, hear that good news of free redemption proclaimed in the power of His Holy Spirit, THEY WILL BELIEVE! Acts 13:48 declares, "And when the Gentiles heard this, THEY WERE GLAD, and glorified the word of the Lord: AND AS MANY AS WERE ORDAINED TO ETERNAL LIFE BELIEVED."
