So back to the challenge.
What Scripture reveals a MAN RECEIVED Salvation and his SALVATION was taken away.
I can’t find any scriptures to back that .....
What I “ DO” have is this—- It PROVES just the opposite ....
John 5:24.......”Anyone who hears my word and believes the One who sent me already HAS Eternal life and shall NOT come Under Condemnation”
Ain’t heard anybody make an effective case against that—Ever!
The only point that I would make about John 5:24 is that it only applies to those who have a heart faith that is unto righteousness (Romans 10:10) and enduring to the end (Matthew 10:22, Hebrews 3:6, Hebrews 3:14).
If anyone has a nominal, lukewarm, or shallow faith, they can fall away (Luke 8:12-13) and those who fall away from faith do not continue to have salvation.
For we have access by faith into this grace wherein we stand (Romans 5:1-2) and therefore if we lose faith, we lose access to grace.
And since we are saved by grace (Ephesians 2:8-9), we lose salvation if we no longer have access to grace.
However, those who have a heart faith that is unto righteousness and enduring to the end are sealed by the Holy Spirit (Ephesians 1:13-14, Ephesians 4:30, 2 Corinthians 1:22, 2 Corinthians 5:5) and therefore, the faith that is instilled in them by the Holy Spirit is in them everlastingly.
Therefore they have everlasting life (John 6:47)...which is life that can never come to an end...otherwise it would have been defined as temporal.
But for those whose faith is temporal, the life that they have is also temporal. These are the ones who are described in Luke 8:13.
