The heart of man may be the abode of the Holy Spirit. The peace of Christ that passeth understanding may rest in your soul, and the transforming power of His grace may work in your life, and fit you for the courts of glory. But if brain and nerve and muscle are all employed in the service of self, you are not making God and heaven the first consideration of your life. It is impossible to be weaving the graces of Christ into your character while you are putting all your energies on the side of the world.
You may be successful in heaping up treasure on the earth, for the glory of self; but "where your treasure is, there will your heart be also" (Matthew 6:21). Eternal considerations will be made of secondary importance. You may take part in the outward forms of worship; but your service will be an abomination to the God of heaven. You cannot serve God and mammon. You will either yield your heart and put your will on the side of God, or you will give your energies to the service of the world. God will accept no half-hearted service.
"The light of the body is the eye: therefore when thine eye is single, thy whole body also is full of light" (Luke 11:34). If the eye is single, if it is directed heavenward, the light of heaven will fill the soul, and earthly things will appear insignificant and uninviting. The purpose of the heart will be changed, and the admonition of Jesus will be heeded. You will lay up your treasure in heaven. Your thoughts will be fixed upon the great rewards of eternity. All your plans will be made in reference to the future, immortal life. You will be drawn toward your treasure. You will not study your worldly interest; but in all your pursuits the silent inquiry will be "Lord, what wilt thou have me to do?" (Acts 9:6).--Review and Herald, Jan. 24, 1888. YSP 48
Press with determination in the right direction, and circumstances will be your helpers, not your hindrances. COL 332
Then I looked on all the works that my hands had done And on the labor in which I had toiled; And indeed all was vanity and grasping for the wind. There was no profit under the sun. Ecclesiastes 2:11 (New King James Version
