Piling A Double Load On Other Men's Shoulders

This is a major problem in apologetics, as in other contexts:

"This is the age of proxy. People are not charitable, but they beg a guinea from somebody else to be charitable with. It is said that charity nowadays means that A finds B to be in distress, and therefore asks C to help him. Let us not in this fashion shirk our work. Go and do your own work, each man bearing his own burden, and not trying to pile a double load on other men's shoulders. Brethren, from morn till night sow beside all waters with unstinting hand." (Charles Spurgeon)
