The New King James Version versus the King James Bible

NKJV: Acts 17:29 "Therefore, since we are the offspring of God, we ought not to think that the Divine Nature is like gold or silver or stone, something shaped by art and man’s devising."
KJB: Acts 17:29 Forasmuch then as we are the offspring of God, we ought not to think that the Godhead is like unto gold, or silver, or stone, graven by art and man’s device.
["Divine Nature" is wrong the KJB has "Godhead" which is correct]

NKJV: Acts 7:45 "which our fathers, having received it in turn, also brought with Joshua into the land possessed by the Gentiles, whom God drove out before the face of our fathers until the days of David,"
KJB: Acts 7:45 Which also our fathers that came after brought in with Jesus into the possession of the Gentiles, whom God drave out before the face of our fathers, unto the days of David;
NKJV: 1 Cor 1:18 "For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God."

KJB: 1 Cor 1:18 For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.
["are being saved" a huge error! Your either saved or Your not]

There are many errors in the NKJV

Proverbs 30:5 Every word of God is pure: he is a shield unto them that put their trust in him.
2 Corinthians 2:17 For we are not as many, which corrupt the word of God: but as of sincerity, but as of God, in the sight of God speak we in Christ.
