I thought this might pertain well to this subject:

A sign hanging on a wall says “CHRIST: the unseen guest in every room”. The first time I saw it was comforting and convicting at the same time. For some reason it triggered in me the recollection of my total depravity and total inability to save myself or to even make myself a better person, and therefore why I have to have Jesus (and so glad I DO have Him), and why everyone else needs Him too.
