Firm. . .

Though continually pressed by the current of the world, it stands unmovable through flood and storm, cold and heat. It never gives a word of complaint because of where it is placed. It has become solid through fire and flood. Although it dwells in the water it does not seek to be like the water, instead it keeps it's clear identity. It has been beaten and scared, yet it utters not a word. And it stands because it is founded on the eternal Rock . . .

"As the truth is brought into practical life, the standard is to be elevated higher and higher to meet the requirements of the Bible. This will necessitate opposition to the fashions, customs, practices, and maxims of the world. Worldly influences, like the waves of the sea, beat against the followers of Christ to sweep them away from the true principles of His meekness and grace; but we are to stand as firm as a rock to principle. It will require moral courage to do this, and those whose souls are not riveted to the eternal Rock will be swept away by the worldly current. We can stand firm only as our life is hid with Christ in God. Moral independence is wholly in place when opposing the world. By conforming entirely to the will of God, we shall be placed upon vantage ground, and shall see the necessity of decided separation from the customs and practices of the world."

(Ellen White, Testimonies, Vol. 6, pg. 146)

We are to be  firm. . . 

. . .as a rock.
