The new war on terror has many people asking, "Who is this Allah?" The pope says that Allah and Jehovah are the same god. President Bush and Ophra Winfrey call Islam a peace-loving religion. This confusion is made worse by Bible translators who have translated the English word "God" as "Allah" in Arabic Bibles.
The Bible says that those who call upon the name of the Lord shall be saved. So what name shall we use? We had better get it right if our eternal destiny depends on it.
If the pope is right and Christians, Jews and Muslims all worship the same God, only under different names, then Jesus was wrong in John 14:6 when He said that "no man cometh to the Father, but by me."
Peter was also wrong on the day of Pentecost when he told the curious crowd that the Jesus they had crucified was the one they were to call on for salvation. He repeated the same declaration a few days later in front of the Sanhedrin that there was "...none other name under heaven given among men, whereby we must be saved." (See Acts 2 through 4.)
Throughout the Old Testament, the idea of God's name being special, holy, not to be profaned, is continually emphasized by the prophets. God was jealous when the people worshipped or served any of the other pagan deities. He didn't say, "Its okay to worship, Molech, Tammus, or Baal. That's just Me by another name."
The Allah of the Koran is not the God of the Bible. They are two very different personalities. The modes of worship and rules of life are opposite and contradictory.
The God of the Bible appears to care very much who we call upon for salvation. So should we.
