Will one go to heaven if he does not believe in Jesus?

No.

Jesus, the alpha and the omega, the one, the universal being who is one and all, the beginning and the end, the timeless and eternal.

If one does not believe in Jesus, of course, the only place is hell and suffering. There will be no liberation from confusion.

That is what constitutes a belief in Jesus.

This is wholly different from simply uttering 'I believe in Jesus' and thinking one is saved.

Reflect and Understand.
