The
consequence of unrepented egregious sin is the loss of eternal life. If a person
loves Jesus Christ, he
obeys his commandments. There is no separation between the two. Jesus Christ only gives the crown of eternal life to those who are still loving/obeying God until their death.
James 1:12
When a Christian sins an egregious sin, he
rejects/spurns Jesus' gift of saving grace.
He tramples upon it, profaning it as if it were a worthless gift. If he does not repent before he dies, God will pour out his wrath upon him in hellfire.
John 3:36, Romans 2:7-8
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 who has spurned the Son of God, and profaned the blood of the (new) 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.”
Titus 1:16
They profess to know God, but they deny him by their deeds; they are detestable, disobedient, unfit for any good deed. Matthew 10:32-33
What saves/justifies us is grace. Jesus firstly gives us this saving grace as his gift to us.
However, in order to continue in the grace/kindness of God and receive eternal life, we must obey his commandments until we die.
Romans 11:22
Note then the kindness and the severity of God: severity toward those who have fallen, but God’s kindness to you, provided you continue in his kindness; otherwise you too will be cut off.
Revelation 2:10
Do not fear what you are about to suffer. Behold, the devil is about to throw some of you into prison, that you may be tested, and for ten days you will have tribulation. Be faithful unto death, and I will give you the crown of life.
I don't think continuing this discussion would be fruitful for either of us.
