Rev, you show me no biblical evidence to go against what I have shared.nope, just because you use the debate tactic of accusing me of arguing around it prior to my response doest negate my response as you wish.
you pointed out that salvation is only by the grace of God and on that we agree. Simply adding, after that, that it would be a work and contrary to grace is only a claim with no evidence.
Confession always comes after salvation (God graciously making a person alive, even when they were dead - Ephesians 2:1-9). It is never an action that causes God to save somebody.
Therefore, since confession comes after salvation, it is an effect of salvation and is not a work.
However, if you demand confession come first...as a necessary requirement for salvation...then you have removed grace as the means of salvation and replaced it with a legal work of the law.
