For Paul, sound doctrine is more than truth propositions; they are ideas that lead to proper Christian activity.
Do not let your life go wasted in pursuing things that Christ already won for us.
That’s the thing about real faith: it’s not a feeling – it’s an action. Of course there are emotions associated with it – apprehension, exhilaration, anticipation. But the bottom line is that faith is not real if it does not produce results.
You probably haven’t ever been whipped or imprisoned for your faith. But we all share in weaknesses.
