The best is "were" .
****************************************************
The best depends entirely on the context in which it is used. Specifically in relation to the time it refers to.
In the 'present' context 'were' is correct eg: If Jesus were here, (at this point in time ) he may do or say this.
In the 'past' context 'was' is correct eg: If Jesus was here, (at some point in the past) then perhaps this or that may have happened.
Jesus' disciples
The more correct way to say this would be "It is humbling to be here". You can, as an alternative, say "I am humbled to be here."
"Outside of Jesus" is the correct way to say it.For example: There is no hope for fallen mankind Outside of Jesus."Outside from Jesus" does not work."Apart from Jesus" would be correct as well.For example: Apart from Jesus, there is no hope for mankind.
Yes
If she were here is the answer. 'If she Were Here' is the correct answer but I guess both can be accepted.
Me is correct here.
Yes, it is correct.Example:"Here is John coming up the field."
No it's not correct grammar. You don't say "Myself is here." You say "I am here," so you would say "John and I are here."
here we can say it is Simon Peter.
The correct grammar is "Here are the names of the providers."
Yes. "She has no idea that you are even here." is a correctly formed, gramatically correct sentence.
Well, if you talking about inanimate object, you should say here it goes, and if about person, then here you go :)
