In the World You Will Have Tribulation.

I have told you these things so that in Me you may have peace. In the world you will have tribulation.
John 16:33 

Can it get any clearer than this?  
  ✝  In Me you may have peace.
  ✝  In the world you will have tribulation.

KatieLyn was having tribulation. Her mom said that she was hysterical. Obviously, she was "in the world," meaning that her mind was not set on God.

Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee.
Isaiah 26:3, KJV

Or in modern English:
You will keep in perfect peace all who trust in you, all whose thoughts are fixed on you!
NLT

Or my preference:
"The steadfast of mind You will keep in perfect peace, Because he trusts in You."
NASB 

How could she miss this? How can one grow up, living in a Christian family, going to church weekly, reading the Bible regularly, and yet miss this? 

God is not the author of confusion. Satan is. The night that KatieLyn ran home, she was under satanic attack. Gwen can be as dismissive as she wishes. Or she can spout off more nasty accusations. KatieLyn can dig in as stubborn as a mule. Or she can pretend to ignore it. Their codependent denial of the facts and their strenuous assertions that KatieLyn's flight middle of the night was the first time in six months that she was thinking straight does not make any of it true. All the cliches they spewed forth fly in the face of these scriptures. When your mind is thinking the thoughts that Satan told you, you are not doing the right thing.

A cross reference for this verse, Philippians 4:7, says,
And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus.

Look again at the part that I highlighted: which surpasses all understanding
The tendency on a first-read is to assume that the relative clause modifies the subject, peace. It does do that, but the assumption is that the peace of God is mind-blowing big—too big to understand. But if you focus on "surpasses understanding," then you have skipped over the "all." 

The "all" becomes important because it clues you in that this is a peace that cannot be understood with human reasoning—ALL human reasoning is surpassed. The thing that can be understood with human reasoning is the stuff that you should be trying to guard against. She should have set her mind on Christ and allowed His peace to guard her heart and mind. This, she did not do.

The Lesson
This is another one of those "why it wasn't the right thing to do" posts that I did not feel free to write about last August 28th. The real "KatieLyn" would have jumped to the mistaken conclusion that I was just being "mean" and trying to hurt her.  She really could not know my true motivation; she chose to not know when she chose to not talk. 

But the lesson here is that KatieLyn's heartache and distress were her own doing, prodded along by a mother who had very mixed "feelings" about the marriage (because, although a part of her wanted to be happy for her daughter, a greater part was jealous of losing her.) Still living at home, in the center of this toxic mix,  KatieLyn looked to the world for understanding and found tribulation instead. Because she did not keep her thoughts stayed on what the Lord had told her, she lost her peace. It was easy then for Satan to deceive her. He told her that she lost her peace because marrying Joe was the wrong thing to do. She believed Satan more than she believed the Lord.
