A part of salvation or a fruit? Necessary for salvation or a part of the accomplished act?
Both. How can we say we love the King if we don't obey His commands? If we are to love God with our whole being, what sort of love is it if we just talk? What sort of faith is that? All faith, even to move mountains, is WORTHLESS if it does not have love (1 Cor 13:2). Your faith is not saving faith if it doesn't possess love. But without faith, our good deeds are ALSO not of merit. Thus, we must have both to achieve heaven.
