Peace is not feeling good about a bad situation. Biblical peace is wholeness… mentally, physically and spiritually.
 Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.  And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.  Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.  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.
1 Thessalonians 5:23
 And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ.
We are triune beings: Man is a spirit, who lives in a body and possesses a soul (or will/intellect).
When you leave out the spiritual aspect, you only minister to 2/3 of a person.
We can only have true peace through a relationship with Jesus.
The peace of God gives complete confidence…
One way or another you are giving your mind to a force , good or bad. So set your mind on whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things
The peace in you has to be bigger than the problem you face.
Until you are living in everything that the Lord has for you, you are not walking in wholeness.
God will not only bring you out of whatever you’re facing , but He will completely release you.
 And a certain woman, which had an issue of blood twelve years,  And had suffered many things of many physicians, and had spent all that she had, and was nothing bettered, but rather grew worse,  When she had heard of Jesus, came in the press behind, and touched his garment.  For she said, If I may touch but his clothes, I shall be whole.  And straightway the fountain of her blood was dried up; and she felt in her body that she was healed of that plague.  And Jesus, immediately knowing in himself that virtue had gone out of him, turned him about in the press, and said, Who touched my clothes?  And his disciples said unto him, Thou seest the multitude thronging thee, and sayest thou, Who touched me?  And he looked round about to see her that had done this thing.  But the woman fearing and trembling, knowing what was done in her, came and fell down before him, and told him all the truth.  And he said unto her, Daughter, thy faith hath made thee whole; go in peace, and be whole of thy plague.
Peace puts the enemy right where he belongs!
 Now Peter and John went up together into the temple at the hour of prayer, being the ninth hour .  And a certain man lame from his mother’s womb was carried, whom they laid daily at the gate of the temple which is called Beautiful, to ask alms of them that entered into the temple;  Who seeing Peter and John about to go into the temple asked an alms.  And Peter, fastening his eyes upon him with John, said, Look on us.  And he gave heed unto them, expecting to receive something of them.  Then Peter said, Silver and gold have I none; but such as I have give I thee: In the name of Jesus Christ of Nazareth rise up and walk.  And he took him by the right hand, and lifted him up: and immediately his feet and ankle bones received strength.  And he leaping up stood, and walked, and entered with them into the temple, walking, and leaping, and praising God.  And all the people saw him walking and praising God:  And they knew that it was he which sat for alms at the Beautiful gate of the temple: and they were filled with wonder and amazement at that which had happened unto him.
Jesus recognizes that in every area that we have, we are in need of wholeness.
