Suicide is still a serious sin against God. According to the Bible, suicide is murder; it is always wrong. Serious doubts should be raised about the genuineness of faith of anyone who claimed to be a Christian yet committed suicide. There is no circumstance that can justify someone, especially a Christian, taking his/her own life. Christians are called to live their lives for God, and the decision on when to die is God’s and God’s alone.
