At the separation of the sheep and goats at final judgment, the host of the rejected call out Lord Lord, did we not do many things in your name? He replies depart from me you workers of lawlessness, I never knew you. Why? I was hungry you did not feed me, thirsty you did not feed me. You can see this pretty clearly in James 2 and elsewhere when the rich mistreated to poor at the love feasts. When addressing the Ephesian church Jesus says they have left their first love, I think they had gotten very good at apologetics and defending doctrine but were neglecting the pastoral needs of the church. I mean think about it, how many churches do you know of that doesn't have a pantry.
Ultimately God wants us to be compassionate, to take care of one another. We can be as pious as we like, strict on doctrine and still fall short of the grace of God. God has mercy on us, we must be merciful. God forgave us, we must forgive. I think that's the general idea, mercy isn't something we just passively receive, it must be extended to others. I'm glad so many mega churches have such impressive multi-media centers but I've never seen a thriving ministry that was any good that didn't have some kind of an outreach to the poor and needy.
Grace and peace,
Mark
