Rev.6:1-2 "And I saw when the Lamb opened one of the seals, and I heard, as it were the noise of thunder, and one of the four creatures saying, Come and see, And I saw, and behold a white horse: and he that sat on him had a bow; and a crown was given unto him: and he went forth conquering, and to conquer."
Peter preached this powerful Spiritual message and the gospel went forth which changed the world! "This is the stone which was set at naught of you builders, which is become the head of the corner. Neither is there salvation in any other: for there is none other name given among men, whereby we must be saved." (Acts 4:11-12)
"And by the hands of the apostles were many signs and wonders wrought among the people; And of the rest durst no man join himself to them. And believers were the more added to the Lord, multitudes both of men and women. Insomuch that they brought forth the sick into the streets, and laid them on couches, that at least the shadow of Peter passing by might overshadow some of them." (Acts 5:12-15)
This message in it's entirety reveals the birth of Christianity into that 1st. Century Pagan world.
