Grace in the Present Tense

I want to write about grace in the present tense. Come to think of it, grace is always in the present tense. God has been granting mercy in my life for fifty four years and may continue to do so for many more to come, but whenever he does it is always now and it is always here.  "My frustration was, rather, in discovering that although many modern writers have succeeded in exploring the depths of human darkness and despair and alienation in a world where God seems largely absent, there are relatively few who have tried to tackle the reality of whatever salvation means.... Sin is easier to write about than grace, I suppose, because the territory is so familiar and because, too, it is of the nature of grace, when we receive it, to turn our eyes not inward, where most often writers' eyes turn, but outward... If and when the time ever came,  it would be the presence of God rather than his absence that I would write about, of death and dark and despair as not the last reality but only the next to last." (Buechner)
