Your logic doesn't follow seeing as those born of God do overcome "for everyone born of God overcomes the world. This is the victory that has overcome the world, even our faith. Who is it that overcomes the world? Only he who believes that Jesus is the Son of God." 1John 5:4,5
It is true that 1 John 5:4 says:
"For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world,
even our faith."
But this was not meant to be an exhaustive truth that applies to all who are born again.
How so?
Well, 1 John 5:4-5 has to be read in light of other verses. For the Bible also teaches that one has to endure, overcome, be faithful unto death, resist temptation, and keep themselves in the love of God:
Please read: Hebrews 3:13-14, James 1:12, Matthew 24:13, Revelation 2:7, Revelation 2:10, Revelation 2:11, Revelation 3:5, and Jude 1:21.
The Bible also teaches that believers can fall away.
Here is a general list of verses about falling away:
Ezekiel 18:24
Hebrews 3:12-14
Hebrews 4:11
Hebrews 6:4-9
Hebrews 10:26-30
Hebrews 12:15
1 Timothy 1:18-20
1 Timothy 4:1-7
Galatians 3:1-5
2 Peter 2:20-22
2 Peter 3:17
Matthew 13:18-23
1 Corinthians 10:12
2 Thessalonians 2:3
Here is a list of believers who have forfeited their salvation:
Saul (1 Samuel 16:14) (1 Samuel 31:4)
Demas (2 Timothy 4:10)
The Prodigal Son (Luke 15:11-32)
Judas Iscariot (Psalm 41:9) (Luke 6:16) (Acts 1:25)
Hymenaeus and Philetus (2 Timothy 2:17-18)
Unnamed Christians destroyed by false teaching (2 Timothy 2:17-18)
Many Unnamed Disciples (John 6:66)
Some Younger Christian Widows (1 Timothy 5:14-15)
Some Christians Eager For Money (1 Timothy 6:8-10)
Ananias and Sapphira (Acts of the Apostles 5:1-11)
And here is a list of potential fallen believers:
The Servant Who is Not Looking For Him (Luke 12:45-46)
Recent Convert Who is a Potential Spiritual Leader (1 Timothy 3:6)
The Unforgiving in Heart (Matthew 6:14-15)
Luke Warm Unrepentant Believer (Revelation 3:14-22)
Fruitless Christians (John 15:1-10) (Matthew 25:14-30)
Widows That Live in Pleasure (1 Timothy 5:5-6)
Believers Whose Seed Fell Upon the Rocks (Luke 8:13)
Believers Whose Seed Was Choked by Thorns (Matthew 13:22)
Gentile Believer Who Did Not Have on a Wedding Garment (Matthew 22:1-14) (Revelation 19:7-8)
The Potential Fellow Believer Who Erred From the Truth & Was Converted Back
(James 5:19-20)
For Scripture cannot contradict itself.
For the statement in 1 John 5:4 can be read without it being an exhaustive truth.
Let me give you an example:
Most people think that two African American parents who are dark skinned will always produce a dark skinned child. But this is not always the case. There have been cases where their child turned out to be white. So while generally it is true that dark skinned parents produce dark skinned children and not white children, this is not always true.
You said:
and they do endure to the end (1John 2:19) Once again you have failed to comprehend the nature of regeneration and its effects on one's behavior.
Again, 1 John 2:19 is not an exhaustive truth. That would be like saying all cats are orange.
1 John 2:19 is referring to the gnostic believers that never truly accepted the Lord and His teachings.
This verse is not teaching an exhaustive truth for other kinds of people.
You said:
That affirms my impression of salvation-by-works Christians. Seems you can't imagine doing what is right unless you're threatened with damnation.
And do you not do that today? Do you not respect certain laws of the law based on the fact that there are punishments attached to them?
You said:
As for us born of God we do what is right because it's our nature to do so. The fact that we have eternal life doesn't lead us to live in sin. So once again your argument to reject the reject the grace of God is flawed.
But in your commentary on 1 John 1:8, you basically insulted holiness type Christians because they say that they have stopped from sinning. Note: Again, I believe many holiness type Christians (like myself) do not regard all sin as the same, and so when they refer to how they do not sin, they are referring to grievous sin and not faults of character, or minor transgressions, or falling short of the perfection of God, etc.; Anyways, your statement here is not consistent with what you said in your commentary.
