"Those who gather at camp meetings must be impressed with the fact that the object of the meetings is to attain to a higher Christian experience, to advance in the knowledge of God, to become strengthened with spiritual vigor; and unless we realize this, the meetings will to us be fruitless. 6T 45.5"
"Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ:"
Both passages emphasize growth in knowledge of God and spiritual maturity. While the EGW passage doesn't directly quote Ephesians 4:13, the theme of attaining a higher Christian experience and advancing in the knowledge of God aligns closely with the verse's focus on reaching 'the measure of the stature of the fulness of Christ.'
