God has chosen to give us information about certain sins. One such sin is the sin that leads to death.
1John5.6 If anyone sees his brother committing a sin not leading to death, he shall ask, and God will give him life—to those who commit sins that do not lead to death. There is sin that leads to death; I do not say that one should pray for that. 17 All wrongdoing is sin, but there is sin that does not lead to death.
What is the sin that leads to death? Here Paul is talking about putting a couple out of the Church for open sin. Therefore the sin that leads to death is when someone is excommunicated from the Church.
1Cor5.4 When you are assembled in the name of the Lord Jesus and my spirit is present, with the power of our Lord Jesus, 5 you are to deliver this man to Satan for the destruction of the flesh, so that his spirit may be saved in the day of the Lord.
Paul did this very thing with two men that blasphemed: 1Tim1.20 among whom are Hymenaeus and Alexander, whom I have handed over to Satan that they may learn not to blaspheme.
“Paul’s command to hand a person over to Satan is the act of excommunication. Excommunication purges evil from the church; 1Cor5.13 God judges those outside. “Purge the evil person from among you.” Believers are safe in the hand of God, from which no one, not even Satan, can snatch them; John 10.28 I give them eternal life, and they will never perish, and no one will snatch them out of my hand. 29 My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father’s hand. 30 I and the Father are on. But if a sinner is delivered to the prince of this world, he faces destruction. He no longer enjoys the protection which a caring Christian community provides. When adrift and deprived of spiritual support, he will come to his senses and subsequently repent.”[i]
