To answer the question, "Do all religions lead to God?", let us first define two important words. First of all, religion is nothing more than the study of man's experience. Theology is the study of God. Any clear study of the different religions show that there are major differences between: the nature of God, the Aseity of God, and the transcendence of God. There are religions that say you can become your own god. There is a religion that says that you just keep becoming reincarnated. Some people hold to a religious system that says that if I just do what is right, God will look down from the heavens above and grant me eternal life in heaven because I have been so good. I could go on an on an on, etc.
I have been a casual observer of this religious forum website for about three weeks now. There is a theme that tends to repeat itself over and over again in all of the postings. When a religion is attacked, it is usually Christianity. The deity of Christ is always questioned. The authority of the Bible is under attack. No one ever mentions the other religions in a negative light. Why does this happen? Because Jesus said it would happen. No one concerns themselves with a religious leader who is dead. Why are all the other religious leaders never criticized. Could it be because they are dead and in the grave? There has only been one who has ever conquered death and the grave. Because He lives, He is a threat to people who do not want to repent of their sin. Yes! There are major differences between the religions in the world! To say that all religions lead to God is to take the "broad" view. This is what Jesus said about taking that view. "Enter through the narrow gate; for the gate is wide and the way is broad that leads to destruction, and there are many who enter through it. For the gate is small and the way is narrow that leads to life, and there are few who find it"(Matthew 7:13-14). Again talking about the narrow road Jesus said in the Gospel of John, "I am the way, and the truth, and the life; no one comes to the Father but through Me"(John 14:6).
Here is the major difference; The Cross! The cross itself proclaims a verdict upon fallen man. The cross says that God requires death for sin. However, God, in His son Jesus Christ, has given us a substitution. Jesus Christ died on the cross, shed His blood, and provided atonement and forgiveness of sins for all who would believe in Him for salvation. The Gospel of Jesus Christ is so different from other religions because it confronts and exposes man for what he really is, and that is a sinner. There is nothing about the cross that fits comfortably with how mankind views himself or his religion. The Gospel does cover the eternal issue of the fact that he is damned and desperately needs to be rescued. The question is not, Do all religions lead to God? The question is, How can an unjust man stand in the presence of a Just and Holy God? However, if any of these words are foolishness to you, I can understand. The Bible says,
For the word of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God (1st Corinthians 1:18).
