Hallelujah, He is risen!
In His word He warns us that many will be unbelievers. What makes HIM the only one for me is not the Bible, which is His unerring word, but it is that He has spoken to me many times. Before you ask, no I have never heard His voice... with my ears. But I have many times "heard" His guidance for my life with my spiritual heart. If you wish to know about God and His Son, our Lord and Savior, why don't you ask Him? But, if you truly desire to know Him, then be respectful and quiet your mind, open your heart and listen. He will answer you, if you're not interested in being sincere and serious then believe what you choose. Perhaps you should read 1 Kings 18:20-40.
The Lord tells us, " be in the world, but not of the world". In other words don't do what the world does just because that's what the world does. Don't be a follower of the world!
