"***** Parents should keep ever before their minds the object to be gained—the perfection of the characters of their children. Those parents who educate their children aright, weeding from their lives every unruly trait, are fitting them to become missionaries for Christ in truth, in righteousness, in holiness. He who in his childhood does service for God, adding to his “faith virtue; and to virtue knowledge; and to knowledge temperance; and to temperance patience; and to patience godliness; and to godliness brotherly kindness; and to brotherly kindness charity” ( 2 Peter 1:5-7 ), is fitting himself to hear and to respond to the call, “Child, come up higher; enter the higher school.” CT 162.1"
"And beside this, giving all diligence, add to your faith virtue; and to virtue knowledge; And to knowledge temperance; and to temperance patience; and to patience godliness; And to godliness brotherly kindness; and to brotherly kindness charity."
Ellen White directly references 2 Peter 1:5-7 in this passage.
