What does it mean to have peace always in our lives?

The sermon highlights that the peace of God is constant and unchanging, regardless of external circumstances. It states that this peace is not dependent on human actions or feelings; it is grounded in the faithfulness of Christ. Therefore, the 'peace that passeth all understanding' remains with believers continually, emphasizing that no one can rob them of this peace as long as they are in Christ. This peace provides believers comfort in trials and reassures them of their eternal security, as stated in John 14:27, where Jesus promises a peace that is unlike the world offers.
