"do in order to perfect holiness in the fear of God. Temperance in eating must be practiced before you can be a patient man. Remember that you have given to your children, in a great degree, the stamp of your own character. You should guard yourself, and not be harsh, severe, or impatient. Deal with them decidedly, yet patiently, lovingly, pityingly, as Jesus has dealt with you. Be careful how you censure. Bear with your children, yet restrain them. This you have neglected too much. You have not corrected them in the right manner, not having perfect control of your own spirit. A great work must be done for you both. 2T 405.1"
"Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God."
The phrase "perfect holiness in the fear of God" is a direct quote from 2 Corinthians 7:1, making this an explicit allusion.
"And, ye fathers, provoke not your children to wrath: but bring them up in the nurture and admonition of the Lord."
Both passages address the proper way to raise children. Ephesians 6:4 warns against provoking children to wrath, while the EGW passage advises parents to be patient, loving, and restrained in their discipline. The connection is a clear thematic parallel.
