Adam and Eve dared to transgress the Lord's requirements, and the terrible result of their sin should be a warning to us not to follow their example of disobedience....There is no genuine sanctification except through obedience to the truth. Those who love God with all the heart will love all His commandments also. The sanctified heart is in harmony with the precepts of God's law; for they are holy, just, and good.
No one who truly loves and fears God will continue to transgress the law in any particular. When man transgresses he is under the condemnation of the law, and it becomes to him a yoke of bondage. Whatever his profession may be he is not justified, which means pardoned.
"The law of the Lord is perfect, converting the soul." Through obedience comes sanctification of body, soul, and spirit. This sanctification is a progressive work, and an advance from one stage of perfection to another.
Let a living faith run like threads of gold through the performance of even the smallest duties. Then all the daily work will promote Christian growth. There will be a continual looking unto Jesus. Love for Him will give vital force to everything that is undertaken. Thus through the right use of our talents we may link ourselves by a golden chain to the higher world. This is true sanctification, for sanctification consists in the cheerful performance of daily duties in perfect obedience to the will of God.
When it is in the heart to obey God, when efforts are put forth to this end, Jesus accepts this disposition and effort as man's best service, and He makes up for the deficiency with His own divine merit. ML 250
He who longs to be of service to Christ is so quickened by the life-giving power of the Sun of Righteousness that he is enabled to bear much fruit to the glory of God. DA 251
Sanctify yourselves therefore, and be ye holy: for I am the LORD your God. And ye shall keep my statutes, and do them: I am the LORD which sanctify you. Leviticus 20:7-8 (King James Version)
