Not only is suicide a sin, it is the sin. It is the ultimate and absolute evil, the refusal to take an interest in existence; the refusal to take the oath of loyalty to life. The man who kills a man, kills a man. The man who kills himself, kills all men. As far as he is concerned he wipes out the world.
Woe to the suicides! I believe that there can be none more miserable than they. Oh, there are some who remain proud and fierce even in hell, in spite of their certain knowledge and contemplation of the absolute truth; there are some fearful ones who have given themselves over to Satan and his proud spirit entirely. For such, hell is voluntary and ever consuming; they are tortured by their own choice. For they have cursed themselves, cursing God and life. And they will burn in the fire of their own wrath forever and yearn for death and annihilation. But they will not attain to death.
...as soon as we examine suicide from the standpoint of religion we immediately see it in its true light. We have been placed in this world under certain conditions and for specific purposes. But a suicide opposes the purpose of his creator; he arrives in the other world as one who has deserted his post; he must be looked upon as a rebel against God. God is our owner; we are his property; his providence works for our good.
Irrevocable commitment to any religion is not only intellectual suicide; it is positive unfaith because it closes the mind to any new vision of the world. Faith is, above all, openness - an act of trust in the unknown.
There is a time in every man's education when he arrives at the conviction that envy is ignorance; that imitation is suicide; that he must take himself for better, for worse, as his portion; that though the wide universe is full of good, no kernel of nourishing corn can come to him but through his toil bestowed on that plot of ground which is given to him to till. The power which resides in him is new in nature, and none but he knows what that is which he can do, nor does he know until he has tried.
And Levin, a happy father and a man in perfect health, was several times so near suicide that he hid the cord, lest he be tempted to hang himself, and was afraid to go out with his gun, for fear of shooting himself. But Levin did not shoot himself, and did not hang himself; he went on living.
