For Jesus is the one referred to in the Scriptures, where it says, `The stone that you builders rejected has now become the cornerstone.' There is salvation in no one else! God has given no other name under heaven by which we must be saved." (Acts 4:11-12 NLT)
If you think that "all roads" lead to God then you really need to consider these verses carefully. They make it perfectly clear that there is "no other name" and "no one else" that can save, but Jesus. If you want purpose for life, pardon for sins, and peace about eternity, you'll have to come by way of Christ's cross and empty tomb.
