Have you ever been in a place where you have no words? A time where you know the presence of Jesus is so strong with you, that you are in awe? You can not describe to others what it feels like, unless they have been in that place.
To know that it is your season. To know He is guiding you and ordering your steps. You see the manifestation of what He has promised you in your life.
You have no words, yet you are so full of joy and peace. You have no words, yet you have so many that you want to express to God. You have no words, so you just break out in worship.
Truth is, you do not need any words, because God knows your thoughts. He know the overwhelming joy that you have, He gave it to you. He know the peace you have because he gave it to you.
So, although you have no words, God knows exactly what you are saying.
Prayer gives you power to walk on purpose
