There are many possible factors as to why a church may have members that don't give their money sacrificially to meet needs. Many of these factors are problems. But the root of the problem is that we don't love God enough. Love will fuel us to give sacrificially. We will make the most sacrifices for what we love. And if we truly love Christ, there will be proof of it and we will express it. The proof and expression will be in what we sacrifice for Him.
