As impossible as it is for us to take a breath in the morning large enough to last us until noon, so impossible is it to pray in the morning in such a way as to last us until noon. Let your prayers ascend to Him constantly, audibly or silently, as circumstances throughout the day permit.
God alone fully understands what each one of us needs; we make mistakes continually and pray for things which would be harmful to us if we received them. Afterwards we see our mistakes and realize that God is good and wise in not giving us these things, even though we plead ever so earnestly for them.
