Charles Hodge, a nineteenth-century Princeton theologian, gave us this tender example of a continuous prayer.
In my childhood I came nearer to “Pray without ceasing” than in any other period in my life. As far back as I can remember, I had a habit of thanking God for everything I received, and asking him for everything I wanted. If I lost a book, or any of my playthings, I prayed that I might find it. I prayed walking along the streets, in school and out of school, whether playing or studying. I did not do this in obedience to any prescribed rule. It seemed natural. I thought of God as an everywhere-present Being, full of kindness and love, who would not be offended if children talked to him. I knew who cared for sparrows. I was as cheerful and happy as the birds and acted as they did.
from A Praying Life, by Paul Miller, 72.
Philippians 4:6–7 (ESV)
6 do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God.
7 And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus.
