POsitionally, yes, of course. They are "in Christ" and have His imputed righteousness. But Eph 1:4 isn't about being chosen to be in Christ, as so many Calvinists seem to believe, from what they all say.
1:4 is about believers being chosen to be holy and blameless. This speaks to experential sanctification, not positional truth.
Consider this:
Colossians 1:22
yet He has now reconciled you in His fleshly body through death, in order to present you before Him holy and blameless and beyond reproach
Colossians 1:23
if indeed you continue in the faith firmly established and steadfast, and not moved away from the hope of the gospel that you have heard, which was proclaimed in all creation under heaven, and of which I, Paul, was made a minister.
Note the bolded part. The verses are saying that God has reconciled believers (you) in order to (for the purpose of) present you (believers) before Him holy and blameless IF YOU CONTINUE IN THE FAITH. That's real clear. There is a condition noted here, and the wording here is very similar to Eph 1:4 about being holy and blameless before Him.
iow, the ONLY way for believers to be presented before Him holy and blameless is IF they continue in the faith.
Yes, from Rom 8. But we're dealing with Eph 1:4, and Rom 8 is a different context altogether, making different points than Eph 1:4.
True, but irrelevant to the OP.
In 2 posts, there has been no refutation of what I have exegeted as noted by the parentheses. May I conclude that my exegesis is acceptable to you?
