"Brother A has a strong influence upon the minds of his brethren; they view things largely from his standpoint. He needs to improve in spiritual soundness and be wise in the things of God. He should begin to show an interest in and devotion to heavenly things and to so educate his powers that they may be of service in the cause of God. He needs the armor of righteousness with which to ward off the darts of the enemy. It is impossible for him to obtain salvation unless there is a decided change in the objects and pursuits of his life, unless he exercises himself continually in spiritual things. 5T 281.1"
"Put on the whole armour of God, that ye may be able to stand against the wiles of the devil."
The EGW passage directly references the 'armor of righteousness' and the need to 'ward off the darts of the enemy,' which is a clear allusion to Ephesians 6:11 and the broader passage about putting on the armor of God.
"But refuse profane and old wives’ fables, and exercise thyself rather unto godliness."
The EGW passage encourages Brother A to 'exercise himself continually in spiritual things,' which echoes the sentiment in 1 Timothy 4:7 to 'exercise thyself rather unto godliness.' Both passages emphasize the importance of actively pursuing spiritual growth and devotion.
