Serenity, unmistakably, has God's name written all over it. Calm and peace at a soul-level, particularly when we find ourselves in the midst of a storm, cannot be experienced apart from Him.
Jesus once said, "Peace I leave with you; my peace I give you. I do not give to you as the world gives. Do not let your hearts be troubled and do not be afraid" (John 14:27, NIV).
So what kind of peace does the world give? The world offers "peace" in the form of music and medication, prosperity and powder, vacations and vials, recreation and recyclable bottles. In other words, peace that will eventually wear off. God's peace is quite different. The peace our Heavenly Father offers His children will last forever.
God points out to us in His Word that His peace is so other-worldy that we mortals can't begin to comprehend it. In the book of Philippians we read that the kind of peace we receive from the Heavenly Father transcends all understanding.
That same text goes on to say that the Heavenly Father's peace will guard our hearts and our minds (Phil. 4:7, NIV). Picture that. The Heavenly Father's peace stands guard over our being, warding off all forces that would threaten our sense of serenity. The Heavenly Father's peace is resistant to attack--whether we are endangered by circumstances out of our control, the words and actions of others, or false messages we give ourselves. The world doesn't give peace like that.
No matter how intense the storms of life, there is no need for our hearts to be troubled. There is no reason to be afraid. Lasting peace is found in relationship with our Heavenly Father. It is the serenity we receive from Him that will enable us to accept what we can't understand. It is the courage that He gives that empowers us to change the things we can. It is the wisdom that our Heavenly Father lovingly gives to His kids that equips us to know the difference.
