From eternal ages it was God’s purpose that every created being, from the bright and holy seraph to man, should be a temple for the indwelling of the Creator. Because of sin, humanity ceased to be a temple for God....
God designed that the temple at Jerusalem should be a continual witness to the high destiny open to every soul. But the Jews had not understood the significance of the building they regarded with so much pride.... The courts of the temple at Jerusalem, filled with the tumult of unholy traffic, represented all too truly the temple of the heart, defiled by the presence of sensual passion and unholy thoughts. In cleansing the Temple from the world’s buyers and sellers, Jesus announced His mission to cleanse the heart from the defilement of sin—from the earthly desires, the selfish lusts, the evil habits that corrupt the soul.... Only Christ can cleanse the soul temple.... His presence will cleanse and sanctify the soul, so that it may be a holy temple unto the Lord, and “an habitation of God through the Spirit” (Ephesians 2:22).
By this beautiful and impressive figure God’s Word shows the regard He places on our physical organism and the responsibility resting upon us to preserve it in the best condition. Our bodies are Christ’s purchased possession, and we are not at liberty to do with them as we please. Man has done this. He has treated his body as if its laws had no penalty. Through perverted appetite its organs and powers have become enfeebled, diseased, crippled....
When men and women are truly converted they will conscientiously regard the laws of life that God has established in their being, thus seeking to avoid physical, mental, and moral feebleness. Obedience to these laws must be made a matter of personal duty. We ourselves must suffer the ills of violated law. We must answer to God for our habits and practices. Therefore the question for us is not, “What will the world say?” but, “How shall I, claiming to be a Christian, treat the habitation God has given me?” HP 191
If all our workers were so situated that they could spend a few hours each day in outdoor labor, and felt free to do this, it would be a blessing to them; they would be able to discharge more successfully the duties of their calling. If they have not time for complete relaxation, they could be planning and praying while at work with their hands, and could return to their labor refreshed in body and spirit. Pr 213-214
"Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?" 1 Corinthians 3:16 (King James Version)
