And when you pray, do not heap up empty phrases as the Gentiles do, for they think that they will be heard for their many words. Matthew 6:7 (ESV)
“… instead of seeking to impress or play probability games with the divine ear, we can pray simple, childlike, and even concise prayers to our Father… knowing that we have his ear through Jesus Christ. We ask him for the needs we already know he knows about. He is a Father, bidding his sons and daughters come close to tell him all the requests of their hearts.”
Greg Morse, How not to pray
God could simply exert raw power and snuff Satan out. That would glorify God’s power. But it would not display so clearly the superior worth of Jesus over Satan. That will be displayed as Christ defeats Satan by His death and then by winning allegiance from the saints because of His superior truth and beauty above the ugliness and lies of Satan.

The pathway to maturity and to solid biblical food is not first becoming an intelligent person, but becoming an obedient person. What you do with alcohol and sex and money and leisure and food and computers, and the way you treat other people, has more to do with your capacity for solid food than where you go to school or what books you read.
