If the believers in Gal 5:21 were righteous, Paul would have had no need to warn them of the potentially spiritually-fatal consequences of the their unrighteousness (sin). But Paul is warning ALL believers - including the righteous ones - since righteous believers too can fall into unrighteuosness if they chose to.
False. Those who
practice such sins in Galatians 5:19-21 are not genuine believers/those who are born of God.
1 John 3:7 - Little children, make sure no one deceives you;
the one who practices righteousness is righteous, just as He is righteous; 8
the one who practices sin is of the devil; for the devil has sinned from the beginning. The Son of God appeared for this purpose, to destroy the works of the devil. 9
No one who is born of God practices sin, because His seed abides in him; and he cannot sin, because he is born of God. 10 By this the
children of God and the children of the devil are obvious: anyone who
does not practice righteousness is not of God, nor the one who does not love his brother.
Proverbs 24:16 - For a righteous man may
fall seven times and rise again, But the wicked shall fall by calamity.
Psalms 37:28 - For the LORD loves justice, And
does not forsake His saints; They are
preserved forever; But the descendants of the wicked shall be cut off.
So the warning from Paul in Galatians 5:19-21 is necessary because there are genuine Christians and there are “nominal” Christians and it’s not hard to find them mixed together within various Christian churches that ALL claim to be Christian. It’s also not always easy to tell apart the wheat from the tares. Even Judas Iscariot looked like the real deal to the other disciples, yet Jesus knew his heart and said he is a devil! (John 6:70)
To claim that Paul's warning doesn't apply to all believers is ridiculous.
Since you use the term “believer” loosely and don’t seem to understand the difference between genuine believers and make believers, I’m sure it does sound ridiculous to you.
So in Gal 5, Paul is preaching that faith alone is not enough for salvation, but that righteousness (obedience/holiness) is also required.
False. Paul does not preach “type 2 works salvation.” So how much obedience/holiness must we accomplish and “add” as a supplement to Christ’s finished work of redemption in order to “help” Christ save us? Christ’s finished work of redemption is sufficient and complete to save (genuine) believers. No supplements needed. (Romans 3:24-28)
Paul clearly preaches salvation through faith (rightly understood) in Christ alone. (Acts 13:39; 15:8,9; 16:31; 26:18; Romans 3:24-28; 4:2-6; 5:1; Galatians 2:16; Ephesians 2:8,9; Philippians 3:9 etc..)
Rev 3:4 clearly describes Jesus granting salvation to certain believers who "have not defiled their garments" with unrighteous works (sin/disobedience). In other words, Jesus grants them salvation due to their fath and works (obedience/righteousness/holiness).
Jesus points out the lifeless state of the church in Sardis -
"..you have a name that you are alive, but you are dead." This church may have had a name of being alive, but they were spiritually lifeless. In other words, the church was filled with unsaved people going through the motions of religion who needed to wake up and repent IN CONTRAST with
a few people in Sardis who have
not soiled their garments; and they will walk with Jesus in white.
*White garments are mentioned elsewhere in Revelation. The church at Laodicea mentions
white garments, that you may be clothed, that the shame of your nakedness may not be revealed.(Revelation 3:18). The 24 elders wear
white garments (Revelation 4:4). The martyrs waiting for God’s judgment are given
white robes to wear (Revelation 6:11). The armies appearing with the Messiah also wear
white and clean linen (Revelation 19:14). The great multitude of the saved in Revelation 7:14 wear
robes made white in the red blood of the Lamb. The color paradox makes the point and implies that the color
white stands for God’s people made spiritually pure and justified by Jesus’ blood. That means the few in Sardis who were given white robes had been made right and just before God.
In Revelation 3:5, we read - "He who
overcomes I will never blot out his name from the book of life." The "overcomer" mentioned in this letter to Sardis is the
Believer/Christian. Compare this with 1 John 5:4:
"Everyone who is born of God overcomes the world. And this is the victory that has overcome the world--our faith. So we are saved through faith IN CHRIST ALONE and not by works.
You want to sweep this verse under the carpet because it contradicts your false "faith alone" doctrine.
I’ve swept nothing under the carpet and unlike you, I properly harmonize scripture with scripture before reaching my conclusion on doctrine. It’s you who sweeps multiple verses under the carpet because they contradict your “salvation by works” doctrine.
