"Let pupils be impressed with the thought that the body is a temple in which God desires to dwell, that it must be kept pure, the abiding place of high and noble thoughts. As in the study of physiology they see that they are indeed “fearfully and wonderfully made” ( Psalm 139:14 ), they will be inspired with reverence. Instead of marring God's handiwork, they will have an ambition to make all that is possible of themselves, in order to fulfill the Creator's glorious plan. Thus they will come to regard obedience to the laws of health, not as a matter of sacrifice or self-denial, but as it really is, an inestimable privilege and blessing. Ed 201.1"
"I will praise thee; for I am fearfully and wonderfully made: marvellous are thy works; and that my soul knoweth right well."
Ellen White directly references Psalms 139:14 in this passage.
"What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?"
EGW explicitly connects the idea of the body as a temple (1 Corinthians 6:19) with the understanding of being "fearfully and wonderfully made" (Psalm 139:14). She builds upon both verses to emphasize the importance of caring for one's body as a sacred duty.
