Will a person that is saved, had accepted Jesus, go to hell or heaven if the take their own life?

Jimmy,
The question of suicide is painful because it hurts so many people. It is murder. Therefore God says not to do it (Exodus 20:13).

That being said, suicide is not the unpardonable sin (Mark 3:28-30). Therefore it can be forgiven.

It is possible for a Christian to be so discouraged, blue, and depressed that he can lose perspective and in a moment of weakness commit the sin of suicide. A true believer committing this sin will go to heaven but will not fulfill his purpose here on the earth and therefore foregoes many of the rewards in heaven that might have been his.
