If we disown him,
he will also disown us;
if we are faithless,
he remains faithful,
for he cannot disown himself
(2 Tim 2)
The proponents of “Once Saved Always Saved” like to use part of the above section of scripture to support their view.
They overlook the bit about disowning and highlight the part about God’s faithfulness.
They must read this as if it means faithlessness on our part towards Him doesn’t matter because He will remain faithful towards us regardless.
But that interpretation is undermined by the preceding statements about disowning, and the reality that the latter part of the quote is about God’s faithfulness to HIMSELF (clue is in “he cannot disown himself”).
So no matter how much He desires to see everyone saved, He cannot grant salvation if doing so compromises the righteous aspect His character.
People always prefer to recognise God as love – but aren’t as keen to balance that with His righteousness.
The tension between those two parts of His character is the reason why God’s love for the world was expressed in the giving of His Son and NOT in the giving of salvation without the sacrifice of His Son.
God’s righteousness made it necessary for His love to be costly to HIM.
