A YouVersion devotional about Daniel inspired me to make a concerted effort to pray three times a day. I have not been perfect at that which is good. You do not want to fall into legalism.
By making a concerted effort, I stumbled on just letting it all out when I pray. I thought a lot about King David and how he just put his heart out there when praying. When praying consistently, I realized how I censor myself. I needed to be honest with my cares because God knew they were there.
When making time to pray, I went down the list: God, family, country, self. The God part evolved into honest praise and silent emotions – no words needed. I then realized, “What about friends?” I had to address those. Praying over enemies soothed me, and many of those were for vengeance.
Solomon made a good warning to approach God with care because He is a King. This is especially true with making oaths.
At the end of it, I believe prayer should be completely open. Raw emotions should be given to God. Again, He knows they are there. It is warm, efficient, and productive to just let it all out with your constant focus on God. I think you will discover more of Him that way.
Application for fathers: Take a part of the morning, focus on God, and, without words, just let the emotions out.
