Actually nobody should be talking in terms of “trusting Cruz” or “trusting Walker.”
We should be talking in terms of “trusting God to do something great with Cruz and/or Walker, late-learning flaws and all.” Even if that is to usher in someone who is hypothetically better, and just having the two in the race has elevated the race’s aspirations at this crucial juncture, it certain is not known yet.
Some people are so fixated on the earthly they cannot see the heavenly writing in large letters upon it.
As long as there is no attempt to put them before God, you shouldn't have a problem with that language either.
