Colossians 1.21-23:

And you, who once were alienated and hostile in mind, doing evil deeds, he has now reconciled in his body of flesh by his death, in order to present you holy and blameless and above reproach before him, if indeed you continue in the faith, stable and steadfast, not shifting from the hope of the gospel that you heard, which has been proclaimed in all creation under heaven, and of which I, Paul, became a minister…

When Paul exhorts his readers to “continue in faith, stable and steadfeast, not shifting from the hope of the gospel,” is he encouraging them to believe the Gospel or to be faithful to God’s covenant?

Doesn’t merely asking such a thing demonstrate that it is a faulty and misleading question?
