Julie pretty much said it very well below. Today’s verses: Psalm 4:8; Isaiah 26:3; 2 Corinthians 13:11; Galatians 5:22-23; Philippians 4:6-9; and Hebrews 12:14. Have a blessed day.
Peace is a contented state of heart produced by the Holy Spirit. It is a tranquility of being that is not dependent upon our external circumstances. Peace embraces the very goodness of God in every situation and demonstrates a spirit of thankfulness and rest. Contrary to peace are anxiety, fear, envy, anger, and despair.

Galatians 5:22. But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, 23. Meekness, temperance: against such there is no law.

Those things, which ye have both learned, and received, and heard, and seen in me, do: and the God of peace shall be with you.
Hebrews 12:14. Follow peace with all men, and holiness, without which no man shall see the Lord:
