 No, Jesus is not the only way to salvation and Jesus never said that. What you're referring to is probably John 14.6 in which Jesus says, I am the way, the truth, and the life. No one comes to the Father but by me. What Jesus was saying is that if you follow my way, follow my truth, follow my life, I will lead you to God. You will know what God is like by following my path. The exclusivity of Christ is something many people dispose of and it's attempt to make Jesus more inclusive and palatable. But here's the truth, Jesus didn't say that he was one of many examples that will help lead you towards God. He said that no one would come to the Father except through him. Jesus was not merely a wise teacher who tried to spur people on towards being good people. He was God in the flesh and he said to repent for the kingdom of God is at hand. In 2 Timothy it talks about the fact that there will be people who will not preach sound doctrine and instead will just preach what people want to hear. When you're watching content online, ask yourself if you like what the person is saying simply because it makes you feel good or because it aligns with God's Word.
