Repetitions have diverse uses in Scripture.
In prayer they argue affection.
In prophecy they note celerity and certainty.
In threatenings they note unavoidableness and suddenness
In precepts they note a necessity of performing them.
In truths, like that before us, they serve to show the necessity of believing and knowing them.
J. C. Ryle, Expository Thoughts on the Gospel of John, Vol. 1 (pg. 7).
Without Jesus willingly living the prayer that he taught all of us to pray, the angels would have had nothing to sing about, those tombs would’ve never opened, sin and death would have never been conquered, and we would be the dead walking. Without Jesus living in the same surrender to which he now calls us, there would be no hope of the defeat of sin and no reality of eternal life for all who believe. It is true and valuable to remember that the gospel of Jesus Christ teaches us that the most wonderful things in life come to us not as the result of demand and control, but through sacrifice and surrender. Blessings that you could never achieve on your own come when you humbly and willing pray, “Your kingdom come, your will be done, right here, right now as it is in heaven.” Aren’t you glad that Jesus willingly did on earth what he taught us to do in this prayer?
Paul David Tripp, Come Let Us Adore Him (pg. 65).
The state may tolerate a vague, generic, nonthreatening religion, but there is, as one Revolution-era preacher put it, “nothing more obnoxious to an established religion than the gospel of Jesus Christ.” In the fullness of time, a spiritually-empowered Caesar will decide that gospel preaching shouldn’t happen, if it disturbs the commerce of the silversmiths of Artemis (Acts 19:21-41), and it always does. The kind of religion the state, any state, will support will always be a “God and country” civil religion that supports the agenda of the politicians. That’s true if we hand over the power to outlaw religious convictions and practices or if we expect the government to write prayers for our schools. Do we really believe that unregenerate people can approach God, without a Mediator, to pray? If not, why would we ask the government to force people to pretend to do so?
This sort of agenda can only exist in the illusion of an America that is itself born-again, through and through. That illusion is over, and happily so. Once a religion has become a means to an end, of national unity or public morality or anything else, it is no longer a supernatural encounter with God and is just another program. That’s why we ought to always be wary of government seeking to “bless” us with state-written “nondenominational” prayers or with direct funding for our religious initiatives (which inevitably cut out the gospel-centered heart of these initiatives). A Christless civil religion of ceremonial Deism freezes the witness of the church into something useless at best, pagan at best. Government-run doxology cannot regenerate a soul, or resurrect a corpse.
