If all religions lead to God, then they should agree on fundamental issues. In fact they do not. Some say God is a person; others that there are many gods; others that God is just an impersonal force.
Some say we live once, and then are judged; others say that we are re-incarnated. Some claim this world is real; others claim that “reality” is just an illusion. If all religions have an equal claim to be believed we’re no wiser, because they contradict each other.
If all religions lead to God, you would expect God would have made them similar, but Hindus believe one thing, Muslims another and Christians something else. The sincerity is unquestioned but they cannot all be right. All roads do not go to the same place.
It is here that some of the statements Jesus made need to be examined. He said he came from God and was in fact God in human form. Further more he said, “I am the way and the truth and the life, no-one comes to the Father except through me” (John 14:6). While one may find many interesting and positive things from other religions what Jesus said are either the words of a lunatic or the the Son of God. If the latter, then other religions need to be seen in that light.
Has God given us a reliable way of understanding himself? Jesus said that he came from God to show us what God is like. Maybe the life and teaching of Jesus is worth investigating.
