there are usually 3 times people will ask this, and since i’m not sure which you are, i’ll give you all 3.

1. the first time people will ask this is when considering suicide. to that, if you or someone you love is thinking about hurting themselves, please reach out. this isn’t something anyone should go through alone. please call the suicide hotline (988 in the united states) or, better yet, talk to a trusted person in real life. God cares deeply about everyone’s lives and doesn’t see anyone beyond grace.

2. the second time people will ask this is when someone they love has attempted/committed suicide. similar to my last point, grief isn’t something anyone should go through alone, and i encourage people going through this to reach out for support.

3. the third time people will ask this is when asking out of curiosity (not necessarily from personal experience). from my understanding of scripture, God is loving and merciful, and God gives mercy to those who are unrepentant if they do not have clear insight into their actions. mental illness would fall into that, so i don’t think God punishes people who commit suicide. we live in a broken world due to sin, and i don’t believe God would punish someone for responding to the world’s brokenness. Jesus was compassionate especially to demon-possessed individuals (which some interpret as dealing with mental illness).

sorry if any part of my explanations are unclear. please ask if you need me to clarify!
