God is not impressed with the language of your lips in regard to prayer. Your eloquence and articulation means a lot to people, but little to God. God speaks every language known to man, beast AND insect. Prayers that move God come from the language of your heart. So whether you are a Rhodes scholar or a real scumbag, if you speak from the heart, regardless of HOW it sounds, God is pleased and you have His ear.
Matthew 6:7,8 When you pray, don’t ramble like heathens who think they’ll be heard if they talk a lot. Don’t be like them. Your Father knows what you need before you ask him.
