The only bible answer you have is bible doctrine. He that believeth in me HATH everlasting life, he that believeth not shall not see life, but the wrath of God abideth on him.-John 3:36
Not he who believeth on me, and doth not slay himself….
The question is not if someone DOES this or that will the not go to heaven, the question is WHO GOES TO HEAVEN.
Would someone who commits suicide go to heaven? that depends if he is saved or not. Do saved folks kill themselves left and right…no, but i would not narrow out the pressure and mortal depression for the those out of the will and out of fellowship with God that they have taken thier own lives.
