People who have their "understanding darkened" are those who Paul describes as "Blinded by Satan".
If you read my 2 Threads posted that describe them, you'll note that they are described as "dark lights".
A person who is a dark light, is Galatians 1:8
How do you spot them?
1.) They will teach commandment keeping and self effort in place of the Grace of God.
2.) They will teach that they can lose their salvation.
3. ) They are fallen from Grace.
So then according to you Paul was teaching a gospel different than his own? Oh and by the way your statements in numbers 2 and 3 are contradicting each other. How can someone fall from grace if they can’t lose their salvation? Are they somehow still saved without grace?
But anyway let’s examine your statements here.
1.) They will teach commandment keeping and self effort in place of the Grace of God.
Is Paul teaching commandment keeping here?
“Therefore, laying aside falsehood, speak truth each one of you with his neighbor, for we are members of one another. Be angry, and yet do not sin; do not let the sun go down on your anger, and do not give the devil an opportunity. He who steals must steal no longer; but rather he must labor, performing with his own hands what is good, so that he will have something to share with one who has need. Let no unwholesome word proceed from your mouth, but only such a word as is good for edification according to the need of the moment, so that it will give grace to those who hear. Do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. Let all bitterness and wrath and anger and clamor and slander be put away from you, along with all malice. Be kind to one another, tender-hearted, forgiving each other, just as God in Christ also has forgiven you.”
Ephesians 4:25-32 NASB1995
Or what about here
“Therefore be imitators of God, as beloved children; and walk in love, just as Christ also loved you and gave Himself up for us, an offering and a sacrifice to God as a fragrant aroma. But immorality or any impurity or greed must not even be named among you, as is proper among saints; and there must be no filthiness and silly talk, or coarse jesting, which are not fitting, but rather giving of thanks. For this you know with certainty, that no immoral or impure person or covetous man, who is an idolater, has an inheritance in the kingdom of Christ and God. Let no one deceive you with empty words, for because of these things the wrath of God comes upon the sons of disobedience.”
Ephesians 5:1-6 NASB1995
Now answer this question is Paul teaching commandment keeping here?
2.) They will teach that they can lose their salvation.
Ok is Paul teaching that someone can lose their salvation here?
“If we endure, we will also reign with Him; If we deny Him, He also will deny us;”
2 Timothy 2:12 NASB1995
Or what about here?
“You have been severed from Christ, you who are seeking to be justified by law; you have fallen from grace.”
Galatians 5:4 NASB1995
Or here?
“But if some of the branches were broken off, and you, being a wild olive, were grafted in among them and became partaker with them of the rich root of the olive tree, do not be arrogant toward the branches; but if you are arrogant, remember that it is not you who supports the root, but the root supports you. You will say then, “Branches were broken off so that I might be grafted in.” Quite right, they were broken off for their unbelief, but you stand by your faith. Do not be conceited, but fear; for if God did not spare the natural branches, He will not spare you, either. Behold then the kindness and severity of God; to those who fell, severity, but to you, God’s kindness, if you continue in His kindness; otherwise you also will be cut off. And they also, if they do not continue in their unbelief, will be grafted in, for God is able to graft them in again.”
Romans 11:17-23 NASB1995
Is Jesus teaching that we can’t lose our salvation here?
“If anyone does not abide in Me, he is thrown away as a branch and dries up; and they gather them, and cast them into the fire and they are burned.”
John 15:6 NASB1995
Can you answer these questions or will you ignore them like you always do?
