Peace is not dictated by outer circumstances but rather by the condition of your inner life.
How is your inner life? Where are you planted? And the peace of God which passes all understanding shall keep your hearts and minds through Christ Jesus (Philippians 2:7). You don’t have to understand everything that happens to you as long as you know and believe that it is happening for you. In Romans 8:28, it says that all things work together for the good to them that love God, and to them who are the called according to his purpose. When bad things happen to you, you can still have peace because you know that God is in control of your life, because you belong to him.
Peace in the scriptures is defined as rest, safety, health, harmony and tranquility. We can find rest for our souls in Psalms 116:7, it says, Return unto thy rest, O my soul…. It is God’s desire for our soul to be at ease, or in tranquility. It is in this state, that we find God. A soul in turmoil and unrest cannot receive the things of God. Turmoil on the inside produces turmoil on the outside. So again I ask, how is your inner life?
