Now onto the verse I wanted to mention: 1 Corinthians 3:17. It says, "If any man destroys the temple of God, God will destroy him, for the temple of God is holy, and that is what you are."
Later in this book in chapter 6:19 we are told, "Or do you not know that your body is a temple of the Holy Spirit who is in you, whom you have from God, and that you are not your own?"
Because of the second verse many think the first verse (3:17) is saying that if someone dies by suicide that means he or she is going to hell because the verse does say, "If any man destroys the temple of God, God will destroy him"
This is not what the verse says. Interpreting the verse this way is totally wrong. You have to take the verse in context. 1 Corinthians 3 is not talking about individuals. The whole chapter is talking about a body of Believers -- the temple in this verse means the church.
This verse must not be used to condemn those who have lost their lives to suicide. Suicide is a tragedy. Often, though, it is a symptom of a mental illness. And there are other reasons -- as many as its victims.
I do see suicide as a sin just like many actions we take that are centered on self. But Jesus died to free us from sin and if we've accepted His gift of salvation we do not need to fear that this sin will send us to hell. I am not condoning suicide. God doesn't want us taking our own lives. We are way too precious for that.
