That's not exactly true. People don't go to hell for rejecting Jesus. We are all going to hell as a consequence of sin.
Though some are saved by Jesus.
God disagrees with you:
Nor is there salvation in any other, for there is no other name under heaven given among men by which we must be saved. (Acts 4:12)
If that Scripture is not true, then Jesus died for nothing. His death on the cross was the biggest mistake of all time.
We would all go to hell as a consequence of sin had it not been for Christ's death. Jesus, and only Jesus, gives mankind a way to reconcile with Him and escape the punishment we deserve for our rebellion against God.
Scripture could not be more clear on this subject. Ignore it and disbelieve it at your own peril.
