"For we all stumble many times. If anyone does not stumble in word, this one is a perfect man, able to bridle also his whole body."  (James 3:2).

'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... is a series of mistakes, and he is not the best Christian... 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).

"For the righteous one may fall even seven times, and he will certainly get up;  but the wicked ones will be made to stumble by calamity."  (Prov 24:16).

'If God requires anything of us, we have no right to draw back under the pretext that we are liable to commit some fault in obeying. It is better to obey imperfectly than not at all. ...Aim at a steady mind to do right, go wherever duty calls you, and believe firmly that God will forgive the faults that take our weakness by surprise in spite of our sincere desire to please Him.'  (J. N. Grou).

"Therefore, my beloved brothers, stand firm and immovable, and work for the Lord always, work without limit, since you know that in the Lord your labour cannot be lost."  (1 Cor 15:58 NEB).
