There is no wrong way to pray.
Perhaps the only mistake in the realm of prayer is not to pray at all.
There are many helpful prayer plans and good books on prayer, but ultimately nothing beats simply praying! You can’t do it wrong.
Serving in the church as a leader for as long as I have, the most consistent thing I’ve seen is a lack of confidence in how to pray. Men and women are often uncomfortable and sometimes afraid to pray out loud in a group because they feel they are not very good at it. This often becomes an obstacle to pray much at all, even in private.
It’s important to remove the element of complexity from prayer and replace it with the promise of life-changing power. In the natural realm, it’s kind of like walking. It’s really difficult to go for a walk and “walk wrong,” and the benefits are incredible.
