"how can anyone enter a strong man’s house and carry off his possessions unless he first ties up the strong man? Then he can plunder his house." Matthew 12:29 (NIV)
Men are proud creatures. We don't like to admit weakness or confess we aren't up to the task. Those unconfessed things, sketchy habits, or self-rightous pride are ropes which tie us and bind us.
Jesus Christ teaches us in simple terms... don't get tied up and strapped down. Stay strong in your faith by confessing your sins to one another. Help each other to stay unbound so that evil can not sneak in and plunder your life.
Get in a small group! It's the bottom line model Jesus Christ used for His disciples. Teaching them the best way to prevent the enemy from tying them up and plundering their life.
