“The power made available in the place of prayer is greater than the man that prayed” 

Are you sad or worried about a situation in your life? Does it looks like that thing can not be done or achieved, hence you worry? Prayer is a place where your countenance can be altered and you will receive peace which no man can give. We see the Lord praying and His countenance was altered in the place of prayers. 

Luke 9:29 And as He was praying, the appearance of His countenance became altered (different), and His raiment became dazzling white [flashing with the brilliance of lightning]. (AMP) 

As He prayed, His countenance was changed, He became very different. This can also affect the worry in your heart as the Lord will grant you peace with His countenance. We understand that when God lift His countenance upon us even as we pray, He gives us peace. 

Numbers  6:25 The LORD make his face shine upon thee, and be gracious unto thee: 

6:26 THE LORD LIFT UP HIS COUNTENANCE UPON THEE, AND GIVE THEE PEACE. 

As you pray, the Lord will lift up His own countenance upon you, peace will follow it. We also understand that in prayers peace is gotten as we make our request known to God. 

Philippians  4:6 Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.  

4:7 And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.

In prayer, you obtain peace that mount guard your heart, thereby having your countenance changed. There is more to prayer, prayer is a deeper walk for fellowship with God. No relationship can excel without communication.
