"I Believe in God the Father Almighty, Creator of Heaven and Earth"

What did the Apostles believe about God the Father? (Like, is He more like a father than a mother?) And how "all" is God's "almighty"? Finally, what are we meant to believe about God's role in Creation? Is it as simple as some Bible teachers make it sound? This week we consider the differences it'd make if we believed in Him as we're invited to.
