In the Gospels we see a Christ who, in the dismissing of certainties, shows us what freedom might mean. We see the way in which He enters into people's lives and dissolves an existing situation, whatever it might be. The likelihood was that the condition had promised security, safety, but now Christ challenges the people to leave their nets, or to leave a nice safe tax collectors booth, and follow Him. He says to Peter, James, and John, "Come," and to Matthew, "Stand up, move, walk, come with me." Our God is a God who moves and He invites us to move with Him. He wants to pry us away from anything that might hold us too securely: our careers, our family systems, our money making, our possessions (a house, a car, the next great thing from the world of technology: toys). We must be ready to disconnect from the attachments of this life in order to prepare for the next. There comes a time when the things that were undoubtedly good and right in the past must be left behind, for there is always the danger that they might hinder us from moving forward and connecting with the one necessary thing: Christ Jesus, Himself.
When we hear the call of Christ, "Come follow Me," our response is to walk away from the trappings of this world, into a life of simplicity. A life in which we live for others. A life where we do not build up "treasures" for the self. A life where the self must diminish in order that He might increase.
If today you hear the call of His voice, take up your cross and follow Him.
