Faith without corresponding action is lifeless; it is dead. In other words, it is necessary to act upon what you have seen or heard.
Inner peace comes when our Believing and doing are in alignment. “A house divided cannot stand.” To say you are a Christian and live like the world is to live in a state of turmoil.
The secret to the “peace that passes all understanding” is only found as we do what we have seen and heard of Jesus in Scripture (the Bible).
