Yes, Jesus is the only way to be saved from the righteous judgment of God the Father (Acts 4:12). The reason is because Jesus is God in flesh (John 1:1, 14; Colossians 2:9) and he was the only one who was able to be perfect according to the Law (1 Peter 2:22). Only Jesus was without blemish, without fault, and perfect in all his ways. No mere human who has sinned is ever going to be good enough to make things right with the infinite God of the universe (Romans 3:10-12). God is holy and requires holiness (1 Peter 1:16). He requires perfection because he is perfect. But we have all sinned (Romans 3:23) and our sins separate us from God (Isaiah 59:2). Even our best works are filthy rags before Him (Isaiah 54:6). Therefore, we are not able to do what is necessary in order to please God because we are not holy, not perfect, are separated from Him, and our best deeds are filthy rags. That is why we need Jesus and that is why he's the only way to be saved.
All religions in the world, except Christianity, teach a kind of salvation that requires the individual to perform a level of good works that is mixed with God's kindness. They hope that this "mixture" of God's kindness and man's "good works" will result in the individual being allowed to obtain God's presence in heaven. But in all these other religions, none have a deliverer, a Messiah who is God in flesh who did what we could not do. Jesus did what we could not do.
Jesus has two natures: divine and human. He was divine so we could offer a sacrifice of divine value to God the father. Jesus was human so that he could offer sacrifice on behalf of people. Because he is divine, he's perfect. Because he's perfect is sacrifice on the cross was perfect and sufficient to save people from the righteous judgment of God the Father.
Therefore, Jesus is the only way to be saved. Not only that, there can be no other way to be saved other than by the work of God. After all, we are all sinners, touched by sin in all areas of our lives, and cannot ever be good enough to please God. Not even our sincerity is good enough because sincerity is an appeal to a good quality in the person, which amounts to pride.
No, we have nothing that we can offer the infinitely holy God. The only one who can satisfy God is God. This is why Jesus, second person of the Trinity, is the only way to be saved.
