How well do you know God's word? How much do you apply your mind to getting to know God? Do you know his plan for your life? Do you know Christ's mind? How well do you know God?
Not well enough might be the answer. Actually, for most Christians, that's exactly the answer that I would expect. Yes, this is a sweeping statement! Let me explain though. There are those who don't know enough about God because they don't spend the time getting to know him through studying his word or getting along to church to be taught. There are others who have put the hours in to get to know God and who's minds are blown away (in a good way!) by how much there is to know.
Loving God with all of our minds is about getting to know him better and better so...
know him with all of your mind.
