The scriptures time and time again state that Elohim is faithful (trustworthy) and yet you deny Him this attribute. To be able to gave something as a gift the provder must first possess the gift. "By grace are ye saved through trust. This not of yourseleves it is a gift from Elohim".
Faithful. full=? and yet you suggest He is empty of trust.
There is a difference between being faithful and having faith.
Being faithful means you can be counted on. God can be counted on to do what he promises he will do.
God did not need to have faith in himself. He already knows that he can do anything he wills. There is no thing in which God needs to place trust. Therefore he does not need faith in himself. He is...I AM.
