That ye might walk worthy of the Lord unto all pleasing, being fruitful in every good work, and increasing in the knowledge of God. Colossians 1:10
The truth of God revealed in His Word is to be a living, abiding principle. It is not to be looked upon as an influence among many but that which is set over all others. It will exercise a power over the life and conduct until the whole being is assimilated to the image of the Perfect Pattern, and the human agent is complete in Jesus Christ. “As ye have therefore received Christ Jesus the Lord, so walk ye in him: rooted and built up,” not in self, not after men’s ideas, but “in him, and stablished in the faith, as ye have been taught, abounding therein with thanksgiving. Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ” (Colossians 2:6-8).
Your greatest danger will be that you will not see the need of contemplating the character of Christ with a set purpose to imitate His life and conform your character to His character. You are to show a marked difference between your character and that of the world. “For in him dwelleth all the fulness of the Godhead bodily. And ye are complete in him, which is the head of all principality and power” (Colossians 2:9, 10).
The grand truths of the Bible are for us individually, to rule, to guide, to control our life, for this is the only way in which Christ can be properly represented to our world in grace and loveliness in the characters of all who profess to be His disciples. Nothing less than heart service will be acceptable with God. God requires the sanctification of the entire man, body, soul, and spirit. The Holy Spirit implants a new nature, and molds through the grace of Christ the human character, until the image of Christ is perfected. This is true holiness...
The spirit and word and influence you carry are making impressions upon the minds of others. The atmosphere which surrounds the soul, if it is evil, will be like a spiritual malaria, which will be poisonous to those around. But it is profitable for the soul to have an atmosphere that will be as a savor of life unto life to others. When the soul is weighted with the truth which works by love and purifies the soul, a heavenly atmosphere will pervade the soul. “He that walketh with wise men shall be wise: but a companion of fools shall be destroyed” (Proverbs 13:20). Every soul that claims to believe the truth, should manifest uprightness of character, devotion to God, steadfastness of purpose, and represent the character of Christ in a well-ordered life and godly conversation.—Letter 70, January 13, 1894, to “Brethren in Responsible Positions in the Review and Herald Office.”
