To do works of God are all well and good, but I can still do works of God with the wrong intention, such as pride, or tricky little kids to take candy from me when I’m who knows what. By this term I mean just plain action, nothing else behind it.
Having faith in God is all well and good, however it trumps the works only if it is a “true” faith rather than false faith. By that I mean faith that inspires works, because if I say I have faith and yet I have no works to prove myself, then do I really have a fruitful faith? Does it mean anything?
That’s why we argue faith and good works, because the word faith, as it is thrown around every day, means nothing. Similarly, love and hate, as they are thrown around every day, don’t really mean anything.
If I’m wrong about something, someone correct me. But this is the way it’s made sense to me.
