That I want everyone to understand that it is error to suppose that simply because a person commits suicide, they therefore have lost their eternal soul. That having said that does not mean it is not possible for a person to lose their soul when they’ve been saved. But it is an extremely demanding and difficult thing to lose your soul. If you want to, you can do it. It can be done. And there are people that have done it. (Jack Hayford, The Sin of Suicide, cassette tape #C0124, part 1, emphasis mine.)
Jack Hayford, who rejects eternal security, is wrong about: (1) Self-murderers and (2) Teaching it is an extremely demanding and difficult thing to lose your soul.
To die a suicide is also to die an unrepentant murderer because you can not repent until after the sin and that will no longer be an option for a suicide. Such a person will be lost (Rev. 21:8; 1 John 3:15b). To deny this truth is not beneficial for possible suicides, who need truth, not lies, about self murder and the spiritual ramifications of it.
Also, it is as easy to lose your soul as it is to disown Jesus (Mt. 10:33). The original apostles, minus Judas Iscariot, all disowned Jesus and fell away quickly in one night:
Then Jesus told them, “This very night you will all fall away on account of me, for it is written: ‘I will strike the shepherd, and the sheep of the flock will be scattered.’” (Mat 26:31)
NOTE: It is the sheep who fall away -- NOT the false convert or never saved people! Don't be deceived by Jack Hayford or the once saved always saved crowd. Furthermore, one is in the dangers of hell just for saying to another, you fool:
... But anyone who says, “You fool!” will be in danger of the fire of hell. (Mat 5:22)
It is also clear that one sin can cause loss of salvation. Click Salvation Can Be Lost With One Sin. Hence, Jack Hayford is dangerously wrong and deserves The Skull and Crossbones Award.
