Brothers and sisters, I do not consider myself to have attained this. Instead I am single-minded: Forgetting the things that are behind and reaching out for the things that are ahead, with this goal in mind, I strive toward the prize of the upward call of God in Christ Jesus. – Phil 3:13-14 NET
Yet I argue not
Against Heaven’s hand or will, nor bate a jot
Of heart or hope; but still bear up and steer
It is not by regretting what is irreparable that true work is to be done, but by making the best of what we are. It is not by complaining that we have not the right tools, but by using well the tools we have. What we are, and where we are, is God’s providential arrangement,—God’s doing, though it may be man’s misdoing; and the manly and the wise way is to look your disadvantages in the face, and see what can be made out of them. Life, like war, is a series of mistakes, and he is not the best Christian nor the best general who makes the fewest false steps. He is the best who wins the most splendid victories by the retrieval of mistakes. Forget mistakes; organize victory out of mistakes.
—F. W. ROBERTSON
