The Bible states he was there from the beginning and was the revelation of God in the flesh. Jesus said he is the only way to the Father, no one gets to the father except through him, he and the Father are one. “Before Abraham was, I Am”, just like God told Moses “I Am that I Am.” He had multiple eye witness accounts of his life, death, and resurrection. “In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through him, and without him was not any thing made that was made. In him was life, and the life was the light of men. The light shines in the darkness, and the darkness has not overcome it.” ‭‭John‬ ‭1‬:‭1‬-‭5‬ ‭ “Jesus said to him, “I am the way, and the truth, and the life. No one comes to the Father except through me.” ‭‭John‬ ‭14‬:‭6‬ ‭ “I give them eternal life, and they will never perish, and no one will snatch them out of my hand. My Father, who has given them to me,is greater than all, and no one is able to snatch them out of the Father’s hand. I and the Father are one.”” ‭‭John‬ ‭10‬:‭28‬-‭30‬ ‭ People will say the Bible was tampered with no evidence but won’t acknowledge the fact that their were multiple accounts and eye witnesses while Muhammad was born over 500 years later and Christ knew there would be a time when false prophets would arise and deceive many (Matthew 24:11) Like brother Raghib stated, people covert to Islam because of what they see, but once they encounter Christ that’s when the conversion happens. I suggest you watch his full testimony (Starting at about the hour and 25 minute mark) and understand how deep he and his family were as Muslims, but once he encountered Christ, he knew he was The Way. I hope you are blessed by the video, God Bless!
