The New International Reader's Version (NIrV) is an English language translation of the Bible. Translated by the International Bible Society on the same philosophy as the New International Version, but written in a simpler form of English, the NIRV seeks to make the Bible more accessible for people who have difficulty reading English, for example because they are non-native English speakers.
KJV: "And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory." (1 Timothy 3:16, KJV)
NIV: "Beyond all question, the mystery of godliness is great: He appeared in a body, was vindicated by the Spirit, was seen by angels, was preached among the nations, was believed on in the world, was taken up in glory." (1 Timothy 3:16, NIV)
NIRV: "There is no doubt that godliness is a great mystery. Jesus appeared in a body. The Holy Spirit proved that he was the Son of God. He was seen by angels. He was preached among the nations. People in the world believed in him. He was taken up to heaven in glory." (1 Timothy 3:16, NIRV)
