SUICIDE

I can give you two examples of  Christians that committed suicide and went to heaven.

King Saul committed suicide.

King Saul sought the witch of Endor and she conjured up the spirit of Samuel from the dead and listen to what he says

1 Samuel 28:18-18
Because thou obeyedst not the voice of the LORD, nor executedst his fierce wrath upon Amalek, therefore hath the LORD done this thing unto thee this day.
Moreover the LORD will also deliver Israel with thee into the hand of the Philistines: and to morrow shalt THOU AND THY SONS BE WITH ME: the LORD also shall deliver the host of Israel into the hand of the Philistines.

What does he do latter after the speaking with Samuel

1 Samuel 31:4
Then said Saul unto his armourbearer, Draw thy sword, and thrust me through therewith; lest these uncircumcised come and thrust me through, and abuse me. But his armourbearer would not; for he was sore afraid. Therefore Saul took a sword, and fell upon it.

Saul kills himself and he is with Samuel, a prophet of God who is not in hell.

Further proof Saul was saved

1 Samuel 10:9:
And it was so, that when he had turned his back to go from Samuel, God gave him another heart: and all those signs came to pass that day.

Samson was another who not killed himself and others with him.  He is on the wall of faith in Hebrews so you know he is saved.

Judges 16:29
And Samson took hold of the two middle pillars upon which the house stood, and on which it was borne up, of the one with his right hand, and of the other with his left.

Judges 16:30  
And Samson said, Let me die with the Philistines. And he bowed himself with all his might; and the house fell upon the lords, and upon all the people that were therein. So the dead which he slew at his death were more than they which he slew in his life.

Hebrews 11:32
And what shall I more say? for the time would fail me to tell of Gedeon, and of Barak, and of SAMSON, and of Jephthae; of David also, and Samuel, and of the prophets:
These are a list of men that sought salvation by faith.
