In this world you will have trouble. Peace is not automatic, but it is available to all children of God who wait upon the Lord in prayer Avail yourself of the peace that can be experienced through an intimate relationship with Him. Peace is always a result of intimacy with God. You may have peace in the depths of your soul and at the same time you can have trouble in the world. Jesus wants us to be realistic and to understand that as His followers we are not exempt from problems of every description - but in the midst of them, as we wait upon the Lord in prayer, we may have peace.
Prayer always precedes strength and victory in the midst of tribulation.
This was a strange shout of victory at a moment when he seemed utterly defeated. But this calm utterance of triumph is our Lord's summing up His whole life. His victory is the foundation of our peace, and the assurance of victory over all the problems and difficulties of life. Every time we wait upon the Lord in prayer, becoming intimate with our God, we will always emerge victoriously. There is power in prayer.
