It is always important to go back to foundations. Life grows and becomes more complex and this is the natural order of things. But we can be overwhelmed at times by the complexity of life and of our beliefs. When this happens, we need to return to the basic foundations, to re-adjust our view, to see things clearly once again. In order to safeguard the truth, Christianity of necessity had to develop doctrine. For instance, when people began to distort the nature of Christ, the Church had to articulate, with great exactness, what Jesus’ nature really was. Over two thousand years of development has created much complexity in these doctrines. But in the richness of doctrinal development, we must never forget the foundation.
The first creed of the Church consisted of three words: Jesus is Lord! This meant that Jesus was God and was the controller of all things. His rule, and His rule alone, would bring peace and salvation. As Christians submitted to this rule, they experience His peace.
At times, we too need to come back to this foundational creed and remember that Jesus is Lord of all, i.e., over every aspect of our life. All our needs, our hope, our desires, our fears, our sins… everything is in His hand. As we realize and affirm that He is Lord over all, we begin to experience His supernatural peace.
