“Thou standest by faith; be not high-minded, but fear.” Romans 11.20
“Wherefore let him that thinketh he standeth, take heed lest he fall.” 1 Corinthians 10.12
A man is never in greater danger than when he has just achieved some great success, or gained a great victory. If he is not very much on his guard, his joyous song of thanksgiving will have a chorus of vainglorious self-congratulation. Beginning with recognition of God’s power, and praise and thanksgiving for it, man insensibly puts himself in the place of God, and assumes that his own wisdom and strength brought him the success and the victory. Thus he exposes himself to attack when he is sure to be overcome, since he has separated from the source of power. Only in the Lord Jehovah is there everlasting strength.
“And Joshua sent men from Jericho to Ai, which is beside Bethaven, on the east side of Bethel, and spake unto them, saying, Go up, and view the country. And the men went up and viewed Ai. And they returned to Joshua, and said unto him, Let not all the people go up; but let about two or three thousand men go up and smite Ai; and make not all the people to labour thither; for they are but few. So there went up thither of the people about three thousand men; and they fled before the men of Ai. And the men of Ai smote of them about thirty-six men; . . . . wherefore the hearts of the people melted, and became as water.” Joshua 7.2-5
The story of Jericho and Ai is sufficient answer to those who repeat with as much assurance as though it were Scripture, the saying, “Once in grace always in grace,” the meaning being that if a person is once really walking in the fear of God he can never fall. There can be no question but that the children of Israel did really and fully trust the Lord when they crossed the Jordan and marched round Jericho. God Himself witnessed that they had the righteousness of faith, and His word declares that they gained a glorious victory through faith. Nevertheless it was but a few days afterward that they suffered a serious defeat. It was the beginning of apostasy. Although God afterwards wrought many wonders for them, and showed Himself always ready to do all that their faith would grasp, the whole people of Israel were never again perfectly united to “fight the good fight of faith.” Only for a little season, after the outpouring of the Spirit on the day of Pentecost, were the multitude of them that believed “of one heart and of one soul.” But that the same union and strength in perfect faith will be witnessed again among God’s people on earth, is as sure as the promise of God.
