Are you a slave? That may seem like a silly question. However slave is defined as, "one that is completely subservient to a dominating influence." If we give our full allegiance to anyone or anything then we are slaves of it. If we waste all of our time thinking about past hurt and how we will get revenge, then we are a slave to those thoughts. If we waste the bulk of our money on meaningless things that do not please God then we are a slave to those purchases. No one can dominate us, but we can willingly submit ourselves to people, impulses, or habits. We become a slave to anything that we submit ourselves to.
The only way to be free is to submit yourself totally to Jesus Christ. Submitting to Christ yields freedom! You may be saved, but have you truly submitted to Him as Lord (Master) of your entire life? New life allows us to experience life the way we were made to, in fellowship with God. If you let Christ dominate you, then nothing else will. Now say it like you mean it:
All things are lawful for me,” but not all things are helpful. “All things are lawful for me,” but I will not be enslaved by anything.
