Why does it have to be "the church?" If I donate to some other charity like the Red Cross or St. Judes Childrens Hospital the people I am helping are part of the Lord's flock too. I give to a no-kill animal shelter. God gave us dogs and cats to be our companions and they are part of his flock too. I coached a church league youth basketball team one season. (Not my chuch) If I place a value on my time on the same pay scale as a Phil Jackson or a Coach K I have given a few million dollars in just that one year. We lost in the league championship game. If we had won would my contribution be even more valuable?
