There's a minimum amount of knowledge necessary to be a believer in God, and it can be pretty difficult and dangerous to try and quantify exactly what that knowledge is. A person needs faith in Jesus as their Savior, which is something that even an infant child can have, somehow. The point is that a person doesn't need to understand the nuances of various churches' teachings on communion or historic liturgical structures to be headed into heaven. Just Jesus.
Because of this, people sometimes think they know enough about God. They've got the basics down and they don't need to worry or obsess over it any more. This is...unfortunate.
Imagine that you knew that $1,000,000 was available to you. Would you stop there, with just that piece of knowledge? Would you think it was "good enough" to simply know about the money without doing anything to get it, to have it, to use it, to keep it, to take full advantage of it?
Getting to know God is like doing a connect-the-dot puzzle. You don't stop with one dot. Or two. You don't get to dot 37 of 38 and just stop. (It hurts my brain just to consider a connect-the-dot puzzle that sits incomplete like that.)
Thanks to sin, evil, and consequence, life lies before you like a confusing jumble of dots. Connect them. God is the dots.
Teach me, O LORD, to follow your decrees; then I will keep them to the end.
Give me understanding, and I will keep your law and obey it with all my heart.
Direct me in the path of your commands, for there I find delight. (Psalm 119:33-35)
