Grace is the enable power of Christ to be cleansed of our sins. When I think of grace I like to think of a dam. Now the purpose of a dam is to create energy for a city, but how does it do that? The dam holds back the water and creates a huge amount of pressure. A portion of that pressure is released into a very large duct that flows down and spins large turbines. The spinning of these turbines is what creates the energy that we all use every day. Now without that water, could we spin these turbines by ourselves? No, manpower alone is not nearly enough to create the energy needed. There is just no possible way that a human being by themselves could turn those massive turbines. In this analogy Christ is the strong current created by the water from the dam. Without him we would be unable to turn the turbine to cleanse our lives, only he can do it! None the less we do have control of one part of this process, we can interfere. Sometimes in our lives we sin to a point that we have created so much filth to clog up the duct and not allow Christ's flow into our lives. We must be continually watching to make sure that we do not inhibit this process. Thus, "faith, if it hath not works, is dead, being alone." see James 15 Turbines without the pressure from the water is completely useless. Our lives without Christ? "For the wages of sin is death but the gift of God is eternal life through Jesus Christ our Lord." see Romans 623
