What are we thinking about? And from that, what are we doing? One can be sure that where our heart is, there our head is as well. And the rest of us follows.
That is intimated or made clear in both Jesus’ words as well as in the New Testament letters. Here are a couple places:
Since, then, you have been raised with Christ, set your hearts on things above, where Christ is, seated at the right hand of God. Set your minds on things above, not on earthly things. For you died, and your life is now hidden with Christ in God. When Christ, who is your life, appears, then you also will appear with him in glory.
It doesn’t take long in reading the Bible and specifically the New Testament and Jesus’ call to realize that this life takes all of us. Not part, not just a bit here and there, not even the best part or parts of us. Everything, period. We get into trouble when we think we can work through or attempt to do the hard stuff when our minds have been elsewhere. Why? Because our hearts were taken up with something else.
This can be so subtle. I’m not even thinking about what is clearly and overtly sinful. But this becomes sinful, even in things that in themselves are well and good and have their place. If we are entirely occupied with them.
Where is our head? Well, we have to ask the question, where is our heart? Then confession of our sin should follow. So that we can get our hearts and heads back on track. And follow.
