"My brother, you are naturally independent and self-sufficient. You estimate your ability to do, more highly than it will bear. You pray for the Lord to humble you and fit you for His work, and when He answers your prayer and puts you under the course of discipline necessary for the accomplishment of the object, you frequently give way to doubts and despondency, and think you have reason for discouragement. When Brother W has cautioned and held you back from engaging in church difficulties, you have frequently felt that he was restraining you. 3T 109.1"
"For I say, through the grace given unto me, to every man that is among you, not to think of himself more highly than he ought to think; but to think soberly, according as God hath dealt to every man the measure of faith."
The EGW passage discusses the brother's tendency to overestimate his abilities, which aligns with the warning in Romans 12:3 against thinking too highly of oneself.
