One cannot do a series on peace without including this well-known and well loved passage. Peace is part of the fruit of the Spirit. Peace is not really optional, if you look at it in this sense. We are supposed to seek His Spirit. We are to develop the Spirit in us to resemble Him more each day. Part of that “resemblance” is peace.
Each day, choose peace. Choose to conform your Spirit to His and grow the fruit that shows that we belong to Him.
