Origen on Prayer

Things in themselves so supremely great, so far above man, so utterly above our perishable nature, as to be impossible for the race of rational mortals to grasp, as the will of God became possible in the immeasurable abundance of the Divine grace which streams forth from God upon men, through Jesus Christ the minister of His unsurpassable grace toward us, and through the cooperant Spirit. Thus, though it is a standing impossibility for human nature to acquire Wisdom, by which all things have been established--for all things, according to David, God made in wisdom--from being impossible it becomes possible through our Lord Jesus Christ, who was made for us wisdom from God and righteousness and sanctification and redemption.
