This is very true; we Christians are not given the Judgement Seat in respect to men's souls (but may be given it in legal matters; jury-duty comes to mind) -- instead, Jesus told us to go out and make disciples of all men; furthermore, the mark that is to discriminate the believer from the non-believer is love.
John says that it is impossible to love the unseen God if we do not love the seen brothers, there is some extension to the non-believer if you are loving your Christian-brethren while loving God: God made man in His image, if you love God then why would you not-love those that bear His image?
* The word you want is derived from mete; drop the e and add ~ing to put it in the form you need.
Regarding mete, yeah I saw that after I posted. On the internet I’ve actually spelled of, “uv”. I really wish we could edit posts here, but no site is perfect.
