"***** More harm than good results from the practice of offering prizes and rewards. By it the ambitious pupil is stimulated to greater effort. Those whose mental powers are already too active for their physical strength are urged on to grasp subjects too difficult for the young mind. The examinations also are a trying ordeal for pupils of this class. Many a promising student has suffered severe illness, perhaps death, as the result of the effort and excitement of such occasions. Parents and teachers should be on their guard against these dangers. CT 270.1"
"And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible."
Both passages discuss striving for a reward. The EGW passage warns against the negative consequences of striving for earthly rewards (prizes), while the Corinthians verse contrasts earthly and heavenly rewards. There's a thematic parallel in the concept of striving and reward, but the focus differs.
"***** Attention to form and ceremony should not occupy time and strength that rightfully belong to things more essential. Everything in this age of corruption is perverted to display and outward appearance, but this spirit should not find place in our schools. We should teach Bible manners, purity of thought, strict integrity. This is valuable instruction. If the teachers have the mind of Christ and are being molded by the Holy Spirit, they will be kind, attentive, and truly courteous. If they work as in the sight of heaven, they will be Christian ladies and gentlemen. Their refined bearing will be a constant object lesson to the students, who, though at first they may be somewhat uncultured, will day by day be molded by its influence. CT 270.2"
"Let this mind be in you, which was also in Christ Jesus:"
The EGW passage explicitly mentions having the 'mind of Christ,' which is a direct reference to Philippians 2:5. The surrounding context in EGW further elaborates on what it means to have the mind of Christ in the context of teaching and character development.
"But let it be the hidden man of the heart, in that which is not corruptible, even the ornament of a meek and quiet spirit, which is in the sight of God of great price."
Both passages contrast outward appearance with inner character. The EGW passage emphasizes 'purity of thought, strict integrity' and being molded by the Holy Spirit, while 1 Peter 3:4 speaks of the 'hidden man of the heart' and a 'meek and quiet spirit.' Both advocate for inner qualities over outward show.
