1 John 4:1 Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world. I have C. S. Lewis' book Mere Christianity. When you shine the light of God's Words upon the writings of C. S. Lewis, it becomes clear that he was an unbeliever. Here are a few quotes from his book: In chapter 10 of Mere Christianity, C. S. Lewis wrote, "There are people who do not accept the full Christian doctrine about Christ but who are so strongly attracted by Him that they are His in a much deeper sense than they themselves understand. There are people in other religions who are being led by God's secret influence to concentrate on those parts of their religion which are in agreement with Christianity, and who thus belong to Christ without knowing it." C. S. Lewis has rejected what the Holy Spirit says in 2 John 1:9, "Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ, he hath both the Father and the Son." See also Hebrews 8:10-11. If a person does not know the Lord, then he is not a Christian, he is not saved. A person cannot belong to Christ without knowing Him. In chapter 5 of Mere Christianity, C. S. Lewis wrote, "There are three things that spread the Christ life to us: baptism, belief, and that mysterious action which different Christians call by different names--Holy Communion, the Mass, the Lord's Supper." He also wrote in the same chapter, "That is why He uses material things like bread and wine to put the new life into us." C. S. Lewis believed and taught a false gospel. The Holy Bible teaches that salvation is by God's grace alone through faith alone in the one offering of Jesus Christ alone upon the cross apart from any sacraments or religious rituals. The Holy Spirit says in Galatians 1:8-9, "But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed. As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed." Let him be accursed. This is God's judgment. Romans 16:17 Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them.
