Slavery to Justification

Christians are the best in the world at justifying sin. No matter what the situation is, and no matter how firmly we believe in righteousness, we find a way to sin and push our convictions aside. This is true of every person on the planet every day of their lives. How do we stick to our convictions and resist the ploys of Satan when he is attacking us in our weakest moment? We are all slaves. When you are obsessed with something, you can't stop talking about it and you find yourself intertwined with our master constantly. Lovers are slaves to their affection. Gluttons are slaves to food. Addicts are slaves to their addictions. They cannot help but act out of submission to their master. How do we become slaves to Christ? How do we become so enamored by His love and mercy that we cannot help but act out of our obsessive state? So far, my best guess is find a way to experience the magnitude of God and taste the kingdom. It is like Edmund in the Chronicles of Narnia, when he ate the turkish delight he could not stop eating. He got lost in his desire to continue eating. Once we experience the power of the kingdom we will not be able stop pursuing it to its fullest extent. How have you experienced the kingdom and what have you done to become a slave to Christ?
