“And when you pray, do not keep on babbling like pagans, for they think they will be heard because of their many words. Do not be like them, for your Father knows what you need before you ask him.” ‒Matthew 6:7-8 (NIV)
When I was a brand new believer, the guy who discipled me frequently referred to this verse. If I prayed too long to bless our meal, he would start eating—beginning with the loudest food on his plate! It was funny, but he wanted to make a point. More words doesn’t mean God hears you more, or that He’s more likely to answer your prayer. Babbling on and on and on doesn’t equal a higher probability of answered prayer.
