Proverbs 4:23 – Above all else, guard your heart, for it is the wellspring of life. (NIV 1978)
My Musings – We need to be alert to actions and thoughts that are contrary to our hearts. No matter how insignificant that they may seem. Because eventually they will pollute our hearts. Changes in the heart will almost always affect what you think, how you act and who you are (wellspring of life). It may be a slow process (like erosion) but changes in the heart are harder to correct.
My Advice – Do not kid yourself by thinking that you can brush up against sin and not become entangled. You cannot simply just have a bite, because one bite calls for another. Avoid situations that you know are wrong but are tempted by. Stay away, turn around, flee from them.
