So, is caring for others "the gospel"? Is that evangelism? No, not without the spoken message of the gospel of Jesus... We should never confuse meeting physical needs with sharing the gospel. Caring for others represents the gospel, it upholds the gospel, it points to the gospel, it's an implication of the gospel, but it is not the gospel, and it is not equal to the gospel.
Mack Stiles in Marks of the Messenger (pgs 68-69) eloquently completes my thoughts about free meals without a Gospel conversation.
