through the baptism that Jesus Christ commanded in Matthew 28:18-20. A person becomes Jesus' disciple through this baptism. Baptism cannot ever be undone. A Christian can become an evil Christian and thereby condemn himself to hell, but his baptism is forever. An unrepentant evil Christian will suffer more in hell than a person in hell who never became a Christian.
2 Peter 2:20-22
For if, after they have escaped the defilements of the world through the knowledge of our Lord and Savior Jesus Christ, they are again entangled in them and overpowered, the last state has become worse for them than the first. 21
For it would have been better for them never to have known the way of righteousness than after knowing it to turn back from the holy commandment delivered to them. 22 It has happened to them according to the true proverb, The dog turns back to his own vomit, and the sow is washed only to wallow in the mire. rsv
1 Timothy 5:8
If any one does not provide for his relatives, and especially for his own family,
he has disowned the faith and is worse than an unbeliever. rsv
Hebrews 10:26-30
For if we sin deliberately after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, 27 but a fearful prospect of judgment, and a fury of fire which will consume the adversaries. 28 A man who has violated the law of Moses dies without mercy at the testimony of two or three witnesses. 29
How much worse punishment do you think will be deserved by the man (Christian) who has spurned the Son of God (by deliberate sin such as adultery or fornication), and (thereby) profaned the blood of the covenant by which he was sanctified, and outraged the Spirit of grace? 30 For we know him who said, “Vengeance is mine, I will repay.” And again, “The Lord will judge his people.” rsv
Mark 12:38-40
And in his teaching he said, “Beware of the scribes, who like to go about in long robes, and to have salutations in the market places 39 and the best seats in the synagogues and the places of honor at feasts, 40 who devour widows’ houses and for a pretense make long prayers.
They will receive the greater condemnation. rsv
John 5:13-15
Now the man who had been healed did not know who it was, for Jesus had withdrawn, as there was a crowd in the place. 14 Afterward, Jesus found him in the temple, and said to him, “
See, you are well! Sin no more, that nothing worse befall you.” 15 The man went away and told the Jews that it was Jesus who had healed him. rsv
Nothing is worse than eternity in hell.
Each Christian chooses by his own actions where he will spend eternity.
Romans 6:22
But now that you have been set free from sin and have
become slaves of God, the return you get is sanctification and its end, eternal life. rsv
Matthew 24:12-13
And because wickedness is multiplied, most men’s
(Christians') love
(obedience to God) will grow cold
(cease). 13 But
he who endures to the end (of his life in obedience to God's commandments) will be saved (approved to inherit eternal life). rsv
A person does not love God unless he obeys God. John 14:15, John 14:21
Galatians 6:8
For
he who sows to his own flesh (sins against God's commandments) will from the flesh reap corruption (eternity in hell); but he who sows to the Spirit
(obeys the Holy Spirit's commands) will from the Spirit reap eternal life. rsv
