We don't use this term too often now unless we are talking about a time in history but can it apply to you today? Peter indicated that "a man is a slave to whatever has mastered him." (2 Peter 2:19)
Peter is not specific about this person, who he is, what status he has, where he lives, what he does for a living but he is absolute about the fact that you can become mastered. This word, "slave," identifies bondage, being totally under the hand and power of another. It is a term not of hope but of lack of personal freedom and control over your body and decision making.
And, to what is this person in slavery? The answer is, "to whatever has mastered him." It is not limited to one of the seven deadly sins of Proverbs 6:16-19 (pride, lying, murder, scheming, the rush to do evil, be a false witness, or a dissension maker) or the one of the Ten Commandments of Exodus 20:1-17 (idolatry, cursing, dishonoring of parents, murder, adultery, theft, false testimony, covetousness) or even greed, lust, envy or revenge. It is to the thing that has specifically mastered him; gotten control of his heart.
Anything that masters the heart and turns it away from God to its own desires is that one thing that produces slavery. It leads to ultimate despair, lack of hope, joy and love. It blackens the heart with selfishness.Are you presently in a state of bondage? What is your "anything?" If while reading this you have thought about what it is in your life that has captured your heart in a negative way, then that is what you are a slave to. What will you do about that recognition? Your decision will lead you out to light or deeper into darkness. Choose light.
