When a person sins a mortal sin, sanctifying graces are no longer present in the soul because the person cuts himself off from God’s fellowship. Christ’s sacrifice no longer saves him.
Hebrews 10:26-31 “For if we sin willfully after we have received the knowledge of the truth, there no longer remains a sacrifice for sins, 27 but a certain fearful expectation of judgment, and fiery indignation which will devour the adversaries. 28 Anyone who has rejected Moses’ law dies without mercy on the testimony of two or three witnesses. 29 Of how much worse punishment, do you suppose, will he be thought worthy who has trampled the Son of God underfoot, counted the blood of the covenant by which he was sanctified a common thing, and insulted the Spirit of grace? 30 For we know Him who said, “Vengeance is Mine, I will repay,” says the Lord. And again, “The LORD will judge His people.” 31 It is a fearful thing to fall into the hands of the living God.”
Romans 11:22 “Therefore consider the goodness and severity of God: on those who fell, severity; but toward you, goodness, if you continue in His goodness. Otherwise you also will be cut off.”
We must remain reconciled with God and die with sanctifying grace in our souls in order to inherit eternal life.
John 15:5 “I am the vine, you are the branches. He who abides in Me, and I in him, bears much fruit; for without Me you can do nothing.”
We are cut off the Vine (Christ) if we sin mortal sins.
1 Corinthians 3:17 “If anyone defiles the temple of God, God will destroy him. For the temple of God is holy, which temple you are.”
We are cut off the Vine, Jesus, by mortal sins because God cannot live in defiled temples. When God leaves our souls when we sin mortal sins, then we are no longer justified. We are no longer saved and we will not inherit eternal life. So, if we sin the mortal sins that cause the death of the soul, then we no longer abide in God. He no longer abides in us. Our own free will actions separate us from God.
James 5:20 “let him know that he who turns a sinner from the error of his way will save a soul from death and cover a multitude of sins.”
James is speaking of mortal sins which cause the death (damnation) of the soul.
1 John 5:17 “All unrighteousness is sin, and there is sin not leading to death.”
John is speaking of venial sins. They do not cause the death of the soul.
Romans 11:22 “Therefore consider the goodness and severity of God: on those who fell, severity; but toward you, goodness, if you continue in His goodness. Otherwise you also will be cut off.”
However, if he repents, confesses, etc., then he will again be grafted back onto the Vine, Jesus.
Romans 11:23 “And they also, if they do not continue in unbelief, will be grafted in, for God is able to graft them in again.”
1 John 2:1 “My little children, these things I write to you, so that you may not sin. And if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous.”
Ezekiel 33:12-20 “Therefore you, O son of man, say to the children of your people: ‘The righteousness of the righteous man shall not deliver him in the day of his transgression; as for the wickedness of the wicked, he shall not fall because of it in the day that he turns from his wickedness; nor shall the righteous be able to live because of his righteousness in the day that he sins.’ 13 When I say to the righteous that he shall surely live, but he trusts in his own righteousness and commits iniquity, none of his righteous works shall be remembered; but because of the iniquity that he has committed, he shall die. 14 Again, when I say to the wicked, ‘You shall surely die,’ if he turns from his sin and does what is lawful and right, 15 if the wicked restores the pledge, gives back what he has stolen, and walks in the statutes of life without committing iniquity, he shall surely live; he shall not die. 16 None of his sins which he has committed shall be remembered against him; he has done what is lawful and right; he shall surely live.
17 “Yet the children of your people say, ‘The way of the Lord is not fair.’ But it is their way which is not fair! 18 When the righteous turns from his righteousness and commits iniquity, he shall die because of it. 19 But when the wicked turns from his wickedness and does what is lawful and right, he shall live because of it. 20 Yet you say, ‘The way of the Lord is not fair.’ O house of Israel, I will judge every one of you according to his own ways.”
Examples of Mortal Sins:
Galatians 5:19-21 “Now the works of the flesh are evident, which are: adultery, fornication, uncleanness, lewdness, 20 idolatry, sorcery, hatred, contentions, jealousies, outbursts of wrath, selfish ambitions, dissensions, heresies, 21 envy, murders, drunkenness, revelries, and the like; of which I tell you beforehand, just as I also told you in time past, that those who practice such things will not inherit the kingdom of God.”
