"Did you, Brother D, as a disciple, a learner, of Christ, go to Him in humble, sincere prayer and commit your ways to him? You failed to do this. You did not investigate all your motives and move with carefulness lest you should bring a reproach upon the cause of Christ, your Redeemer. You did not consider whether this move would have an effect to increase your spiritual sensibility, quicken your zeal, and strengthen your steadfastness in the truth and your efforts to deny self. You were ignorant of your own heart. The work of God was seen in the church, but you had no longings for the divine Spirit. The things of heaven were insipid to you. You were infatuated by your new hopes of uniting your interests with those of another. You did not consider that a marriage alliance would vitally affect your interest for life, short though that life must be. 2T 226.1"
"Trust in the Lord with all thine heart; and lean not unto thine own understanding. In all thy ways acknowledge him, and he shall direct thy paths."
EGW's counsel to Brother D to commit his ways to God in prayer and not lean on his own understanding directly reflects the principle outlined in Proverbs 3:5-6.
