First, God is one God, not three or more. One assumption of the whole Bible about God begins at Deuteronomy 6:5, “The LORD our God, the LORD, is one. Love the LORD your God with all your heart, soul, mind, and strength.” The Israelites recited these words from God often. He is one God in contrast with the multitudes of gods of the nations around the people of Israel, who were tempted by those gods and often worshiped them.
Second, that kind of thinking isn’t narrow-minded if God has revealed himself to be one God and the only true one. Of course, as I have shown in other blogposts about the Father, Jesus, and the Holy Spirit, God is also three Persons, a very mysterious Being, yet revealed to us in the Bible, especially in the Gospel of John, as 3-in-1, in other words, as the Trinity. In the light of this teaching, I had to submit my reasoning to God’s reasoning, which is far beyond mine.
Third, all religions believe in different Gods, not the same God. How can I make that claim? Hindus and New Age (Higher Consciousness) adherents believe in a god identified with the universe, not separate from it (for example, the Force in the Star Wars movies). Muslims believe in a one-person God (Allah) or a creative force that created the cosmos. Jews believe in the God of the Old Testament but not of the New Testament in the Bible. My obvious conclusion is that other religions don’t believe in the same God as Christians.
Fourth, Jesus said, “I am the Way and the Truth and the Life. No one comes to the Father except through me.” Yes, Jesus claims in this verse to be God because he says, “I am,” one of seven of such statements in John’s book. He identifies with the God who has revealed himself to Moses in the unburnable burning bush in Exodus 3 and 4. He gives his name as “I AM.” Since Jesus is one of the three Persons of God, he can claim with justification that he is the only Pathway to the Father. Only our personal trust that results in a life following him gives us a ticket to heaven.
