Yes, suicide is a sin. It is a sin because it is a result of lacking faith. And we know from the Bible that anything done without faith is sin.
We live by faith and not by sight. We wake up every day having faith that we can make our lives better even if they are in shambles.
The truth is that the life we live has so many troubles. Job says ‘Man born of woman is of few days and full of trouble’. These troubles are permitted by God to build our faith.
The more we overcome the troubles of every day, the more our faith grows. But if we lose faith, we become fearful of tomorrow.
When someone completely loses his faith, he commits suicide. When faith is depleted, fear is full. The fear of seeing trouble for another day scares people to the point that they prefer to end their lives than face tomorrow.
That is an act of fear which greatly displeases God. That is how suicide is a sin.
Anyone who commits suicide ends up in hell. Jesus suffered more pain than anyone of us will ever suffer. Yet Jesus didn’t commit suicide.
Judas Iscariot committed suicide after betraying Jesus. The act of betraying Jesus troubled him and made him lose hope. How would he fellowship with the other disciples after betraying Jesus?
The fear of living with the shame of having betrayed Jesus pushed him to commit suicide. But God expected Judas to overcome that fear and ask for forgiveness. God would certainly forgive him.
Therefore, for anyone who is suicidal, God expects you to face your fear and hold on to your faith. Don’t be afraid to approach God with your troubles. Jesus asked all who were weary and heavily laden to go to Him that He would give them rest.
Suicide is a sin; hold on to your faith and overcome the devil.
