"***** Let not teachers have favorites among their students, or give to the bright, quick students the most attention. Those who are apparently the most unpromising most need the tact and kindly words that will bind their hearts to the heart of the teacher. CT 318.1"
"But if ye have respect to persons, ye commit sin, and are convinced of the law as transgressors."
Both passages address the principle of impartiality and avoiding favoritism. James 2:9 condemns showing respect to persons, and EGW warns teachers against having favorites among students.
"***** Students should not be so pressed with studies as to neglect the culture of the manners; and above all, they should let nothing interfere with their seasons of prayer, which bring them in connection with Christ. In no case should they deprive themselves of religious privileges. CT 318.3"
"But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you."
The EGW passage directly echoes the principle of prioritizing spiritual connection (prayer and religious privileges) over other pursuits, including studies. This aligns strongly with Matthew 6:33, which urges seeking God's kingdom first. The connection is clear and significant.
