Most of us are pretty good at presenting a Christian face to the world. Underneath the façade, though, our thoughts often reveal a different side to our character. Indeed, getting our thought life under control is far more difficult than mastering our outward habits. John Macarthur once wrote, “The sins of our thought life are soul-coloring sins, character-damaging sins.”
What we think about shapes who we become. We can never be joyful followers of Christ if deceit, lust, and conceit cloud our thoughts. The direction of our lives will be determined by what we think about most. A mind saturated by Jesus will yield a life devoted to Him. As appealing as that sounds, the opposite is also true. When our thoughts are on things other than God, the result will be a life that is frustrated, defeated, and ultimately wasted.
