“Every way of a man is right in his own eyes, but the Lord weighs the heart.” (ESV)
There is absolutely no better salesman on the rightness of what we plan to do than ourselves. We can convince ourselves of literally anything given enough time and motivation. If left to our own devices, we can justify just about any behavior.
One of the most popular slogans of our culture today is to follow your heart. As warm and fuzzy as this advice is made to sound, however (and nobody has worked quite so hard to make it the central thought of every young person than Disney), the truth is that it is awful advice. Absolutely awful.
Because of sin, our hearts are hopelessly corrupt and deceptive. If we follow our own hearts we are going to find our way into nothing but trouble and lots of it. If instead we turn ourselves over to the God who defines right and wrong and let Him be our guide regardless of where our heart is telling us to go, the likelihood of our finding ourselves on the right track goes up enormously.
The Lord weighs the heart. Let us let Him weigh ours so that we stay following after Him on the path to life.
