I was also upright before Him, and I kept myself from mine iniquity. – Psalm 18:23

If when you are in need, if when you are under temptation, God helps you to keep straight, you will come out all right at the last. What a number of stories I might tell here of young men, who were great losers at first by being godly; but they kept themselves right, and they had to thank God for it ever afterwards. I know, at this present moment, a personal friend who was a banker’s clerk. On a certain day, he was told to do something which he judged to be, speaking plainly, dishonest; and he told the manager that he could not do it, whereupon he received a month’s notice. It was a country bank, and he was not sent about his business at once; and he had to turn the matter over. He had a wife and children; and when he went home, it was not easy to tell the wife that the excellent situation that he held would be vacated within a short time. But he stood fast in his integrity, he said that he was sure God would bring him safely through, and he never had even the slightest thought of doing other than he had said he would do. It was within twelve months that he obtained the situation of manager for that very bank, and it belongs to him at this moment; he very speedily became a man in a much better position than he could have expected to have obtained, simply from the fact that it had been proved that he could be trusted. It is not always so; some people have to be a long time under a cloud; but, in the long run, if thou as a child of God wilt but stand fast, God will not let thee be a loser. If He does, it shall be thy glory to lose everything sooner than tarnish thy character. Thou shalt find it a greater joy to lose all things for Christ than it would be to gain the whole world by doing anything that was wrong. If you are able to say, “I kept myself from mine iniquity,” then you shall also be able to say with David, “I will love Thee, O Lord, my strength. The Lord is my rock, and my fortress, and my deliverer. I will call upon the Lord, who is worthy to be praised.” ~ C.H. Spurgeon
