Many of us probably understand at least a little about the way our car runs, right? The engine produces power which, when the car is in gear, is transferred via the transmission to those wheels that propel the car. If the car is taken out of gear, it doesn't matter how much you step on the gas - the car won't go anywhere. I John 1:6-9, "If we say that we have fellowship with Him, and walk in darkness, we lie and do not practice the truth. But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ cleanses us from all sin. If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness." Picture yourself as a car. If you've placed your confidence in Jesus Christ alone for eternal life, a kind of spiritual engine, the Holy Spirit, has been placed inside of you, fueled by God's word, and you are Heaven-bound. The power produced by that engine is transferred through you, propelling you to do God's will.
