It is actually very simple. God desires that you come to Him when you're having trials and struggles, Actually, He'd much rather have you crying in His arms than singing in the church choir. It's during the tears and comfort that the relationship is strengthened.
In simpler terms... As a parent, would you rather that your child show you that they need you or just compliment you to others and to you? I believe that the majority of us would rather have our children come to us when they are hurting and need us than praising us. This shows a willingness to have a relationship.
I really hope that I can take this concept and use it to help each one of my children go to God when they're struggling instead of suffering on their own. Right now, one of my children is suffering greatly and watching the movie The Blindside tonight increased that suffering. I pray that she will turn to God for help and that she will understand that He wants her to cry to Him.
King David is a great example of someone who both praised and cried out to God. Check out the book of Psalms.
Better Than A Hallelujah... Wish I would have thought to put this concept into words. How great it is to have a wonderful and merciful God who loves it when we cry on Him.
Look up the lyrics, it's a great song!
