I don’t see anything in Scripture that authorizes us to kill ourselves because of the sinful world around us. We are instead instructed to pray, do what we can about the situation to the extent it is proper for believers to do so (e.g., publicly assert God’s position on the matter), but ultimately leave it to God.
We leave things to God; the Moslems take it upon themselves to do what they believe to be the will of Allah.
Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God? You are not your own; you were bought at a price. Therefore honor God with your bodies.
