Do you think god cares about the spelling or is it just picky Christians?
Initially no He doesn't care about grammar, but the respect should be made known though. On this site you will come across many different types of petty and nitpicky people. When you type about God especially on a public forum you should do it in a way where not to offend other believers by lower-casing the name. God isn't out to crucify you for putting a little "g" in the name for not knowing or making a mistake, but some members on this site are. I mess up and put little G's here and there every once in a while too because i type well over 95 wpm and i miss the shift key. Anyways, God knows the heart and your intentions, and some on this site only know what they can see. Just be mindful of that though.
With that said welcome back.
