In this way, according to the Bible, suicide is a SIN. It isn't the "best" sin—it is no more terrible than different indecencies, regarding how God sees it, and it doesn't decide if a man's going to hell. In any case, suicide certainly has a profound and enduring effect on those left behind. The Bible says this in these verses: May God concede His beauty to everyone who is confronting trials today (Psalm 67:1).
Furthermore, may each of us take trust in the guarantee, "Everybody who approaches the name of the Lord will be spared" (Romans 10:13). So as long as someone believes in God, they will be saved even though it is a sin.
