“Why let him that thinks he stands take heed lest he fall.” 1 Corinthians 10:12.
If any of us are finally saved, it will be by clinging to Jesus as to the rounds of a ladder. To the believer, Christ is made wisdom and righteousness, sanctification and redemption. Let no one imagine that it is an easy thing to overcome the enemy and that he can be borne aloft to an incorruptible inheritance without effort on his part. To look back is to grow dizzy; to let go the hold is to perish. Few appreciate the importance of striving constantly to overcome. They relax their diligence and, as a result, become selfish and self-indulgent. Spiritual vigilance is not thought to be essential. Earnestness in human effort is not brought into the Christian life.
There will be some terrible falls by those who think they stand firm because they have the truth, but they have it not as it is in Jesus. A moment’s carelessness may plunge a soul into irretrievable ruin. One sin leads to the second, and the second prepares the way for the third, and so on. We must, as faithful messengers of God, plead with Him constantly to be kept by His power. If we swerve a single inch from duty, we are in danger of following on in a course of sin that will end in perdition. There is hope for every one of us, but only in one way, and that is by binding ourselves to Christ, and exerting every energy to attain to the perfection of His character. –Testimony Treasures, vol. 2, pp. 211, 212.
