"On such occasions parents and children should feel free from care, labor, and perplexity. Parents should become children with their children, making everything as pleasant for them as possible. Let the whole day be given to recreation. CT 347.1"
"And he said unto them, The sabbath was made for man, and not man for the sabbath:"
Both passages emphasize that certain times are meant for rest and enjoyment, not for being burdened by work. EGW applies this to parents and children, while Jesus applies it to the Sabbath. The underlying principle of prioritizing human needs over rigid adherence to rules is present in both.
"Exercise in the open air for those whose employment has been within doors and sedentary will be beneficial to health. All who can should feel it a duty to pursue this course. Nothing will be lost, but much gained. They can return to their occupations with new life and new courage to engage in their labor with zeal, and they are better prepared to resist disease.— Testimonies for the Church 1:514, 515 . CT 347.2"
"For bodily exercise profiteth little: but godliness is profitable unto all things, having promise of the life that now is, and of that which is to come."
Both passages discuss the benefits of physical activity, although EGW focuses on outdoor exercise and 1 Timothy 4:8 contrasts bodily exercise with godliness. The connection is thematic but not a direct allusion or principle.
"***** Many allow the youth to attend parties of pleasure, thinking that amusement is essential for health and happiness; but what dangers are in this path! The more the desire for pleasure is gratified, the more it is cultivated and the stronger it becomes. The life experience is largely made up of self-gratification in amusement. God bids us beware. “Let him that thinketh he standeth take heed lest he fall.” CT 347.3"
"Wherefore let him that thinketh he standeth take heed lest he fall."
EGW directly quotes 1 Corinthians 10:12, making this a clear and explicit allusion.
