I've had this same argument with self-appointed missionaries far too many times to waste much time with it now.

A pastor friend of mine once commented, "Some hard-charging evangelists have their minds so set on getting themselves, and everybody they can harass into Heaven that they, themselves, are no earthly good for anything."

This particular pastor's method of evangelizing was to keep his mouth shut (except for sermons in his own church) and show by example.

Iona, Pete, look up Matthew, 25:35-40.

Read it carefully.

Study it.

Then, go live it.

And stop pestering people until you learn to live as Jesus says you should live (see above Scripture).
