Live in harmony with the created order.  Your body and soul gets out of sorts when you allow yourself to be filled with bitterness, anger, unforgiveness and resentment.  Human bodies and spirits work best with the Christian virtues of love, joy, peace, patience, kindness, goodness, faithfulness, meekness and self-control.  That’s the way the Creator made things to function.

“For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse.” Romans 1:20 (NASB)
