The main subject of the Bible is the kingdom which God intends to give to His Son, the Lord Jesus Christ, Who will be crowned "KING OF KINGS, AND LORD OF LORDS," according to Revelation 19:16. Ecclesiastes 8:4 says, "Where the word of a king is, there is power: and who may say unto him, What doest thou?" Unlike the modern versions, the KJV was translated under a king. In fact, the king's name was "James," which is the English word for "Jacob," whom God renamed "Israel," because he had power with God and with men (Gen. 32:28).
The new versions have been translated in America, which is not a monarchy. God's form of government is a theocratic monarchy, not a democracy. Therefore, it makes perfect sense that His word would be translated for the English speaking people under a monarchy with an English king.
