"And let the peace of God rule in your hearts, to the which also ye are called in one body; and be ye thankful."
Peace is the presence of God ruling in your heart in ALL situations.
Peace is not the absence of rain clouds, it is knowing that God will give you shelter from the storm. Peace is walking through the fire, with an attitude of calm and quiet trust.
Peace doesn't consist of a problem free existence.
Peace is not the absence of suffering, but it is a blessed assurance in the midst of suffering, that God is in control.
Peace is simply letting the God of Creation rule as king of your heart and life. Peace does not mean you have a perfect life, it's knowing how to have perfect serenity through it all...
