That is totally incorrect. The Bible calls God the "author of our faith"...so how can He not have faith? In Mark 11 Jesus states "Godlike faith". The issue is that you don't seem to understand what faith is.
You said faith in what? Huh?
In Hebrews the writer states that "Faith is the 'substance' of things hoped for. Faith, according to Jesus, healed the sick, raised the dead,...etc.
In Mark 11 Jesus states , " If you SAY to this mountain...and BELIEVE...it shall happen." Faith is an authoritative belief.
Genesis says that God did exactly what Jesus told us to do. "...SAY to this mountain...and BELIEVE...it shall happen." .....God SAID "let there be light, and there was light"
So yes God DEFINITELY has FAITH. We were created in His image and likeness. So do the math.
