THOU SHALL NOT. The Ten Commandments are vital pillars of Christianity, but building a life entirely on not doing leaves much of God's purpose for your life undone. A fresh look at the Bible reveals significantly more "Thou Shall" callings from God than "Thou Shall Not" directives.
A vibrant Christian life is far more about active faith than passive avoidance of sin. The biblical God is defined by movement and action. Jesus's life teaches engagement, sacrifice, and service. God calls us to go, act, advocate, and serve. THOU SHALL.
