Christians Can Feel Suicidal
Note that some of these passages are from the Old Testament, which predates Christianity. However, these passages describe great Old Testament leaders who worshipped God.
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. (1 Samuel 31:4)
Then Jezebel sent a messenger unto Elijah, saying, So let the gods do to me, and more also, if I make not thy life as the life of one of them by to morrow about this time. And when he saw that, he arose, and went for his life, and came to Beersheba, which belongeth to Judah, and left his servant there. But he himself went a day's journey into the wilderness, and came and sat down under a juniper tree: and he requested for himself that he might die; and said, It is enough; now, O LORD, take away my life; for I am not better than my fathers. (1 Kings 19:2-4)
Oh that I might have my request; and that God would grant me the thing that I long for! Even that it would please God to destroy me; that he would let loose his hand, and cut me off! (Job 6:8-9)
