Do you have trouble with it?
Don't. It's simple.
That's right. Groan.
The Spirit helps us in our weakness, for we do not know how to pray as we ought, but the Spirit Himself makes intercession for us with groanings that cannot be uttered.--Romans 8:26
If we are to pray, we have to want God.
This is not a casual relationship. It's like the desire we have when we first fall in love, when we think we will die every instant, like what we feel will not fit inside our skin.
Reading a book about it won't work.
Have you ever read a book about how to fall in love? And why not?
Because it's not necessary. Love lands on us like a ton of bricks.
No book can explain it.
No lesson can teach it.
It's the same with prayer. We pray because we can't help it, because we can't face a life without God, because He matters more than what we are doing, who we are seeing, and whatever else we are thinking.
That is prayer--the groanings and glories of love.
If you can't pray, don't ask someone to teach you.
Go and find your God.
He will draw you in so close that you won't be able to help it.
