You must have a line since you spout off that a Christian can be lost.
Let's try it a little differently..
Let's say I am a born again Christian, what must I do to be lost?
Once again it is not my line as I do not place the standard between eternal life and eternal death.
That is done by God Himself by His word !!!
Acts 20:28-31
28 Therefore take heed to yourselves and to all the flock, among which the Holy Spirit has made you overseers, to shepherd the church of God which He purchased with His own blood. 29 For I know this, that after my departure savage wolves will come in among you,
not sparing the flock. 30 Also from among yourselves men will rise up, speaking perverse things, to
draw away the disciples after themselves.
31 Therefore watch, and remember that for three years I did not cease to warn everyone night and day with tears.
Colossians 1:22-23
In the body of His flesh through death, to present you holy, and blameless, and above reproach in His sight—
if indeed you continue in the faith, grounded and steadfast, and
are not moved away from the hope of the gospel which you heard, which was preached to every creature under heaven, of which I, Paul, became a minister.
Staying in or returning to a deliberate sinful lifestyle of following after false teachings will not lead a person to eternal life.
*Things Children of God Can Do:
1. Fall from grace - Gal. 5:1-4,13
2. Be led away with error - 2 Pet. 3:17
3. Err from the truth - James 5:19-20
4. Weak brother may perish - 1 Cor. 8:11
5. Fall into condemnation - James 5:12
6. Be moved away from the hope - Col. 1:21-23
7. Deny the Lord who bought them - 2 Pet. 2:1
8. Depart from the living God - Heb. 3:12
9. Can be a castaway - 1 Cor. 9:27
10. Can become accursed children - 2 Pet. 2:14
The words of Jesus are clear...by belief the condemnation has been removed..it is a once for all act....only those who have not believed are condemned John chapter 3......! You cannot lose salvation and again, your verbiage points to the fact that you believe in a self sustained, working for salvation pseudo gospel even though you deny it and or are blind to it!
So do you deny what I just posted from the Apostle John in his first epistle where he clearly showed how we can tell if we have eternal life abiding in us ???
Chapters 2 through 4 clearly shows if you are truly born again with the Holy Spirit what you will do, and the things that those who claim they believe but show differently in their actions do not have eternal life abiding in them.
