"Some in their public labors with the churches are in danger of making mistakes from a lack of thoroughness. It is for their own interest and that of the cause that they should search closely, try their motives, and be certain to divest themselves of selfishness. They should watch lest, while they preach straight truths to others, they fail to live by the same rule, and allow Satan to substitute something else for the deep heartwork. They should be thorough with themselves and with the cause of God lest they work for wages and lose sight of the important and exalted character of the work. They should not let self rule instead of Jesus, and they should be careful not to say to the sinner in Zion, It shall be well with thee, when God has pronounced a curse upon him. 1T 468.2"
"But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway."
Both passages address the danger of preaching without personal integrity and the risk of being disqualified despite outward service. Paul's concern about becoming a 'castaway' after preaching aligns with White's warning against failing to live by the same rules preached to others.
"Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother’s eye."
Both passages emphasize the importance of self-examination and addressing one's own flaws before attempting to correct others. The principle of dealing with one's own 'beam' before addressing another's 'mote' directly relates to White's call for thoroughness and self-examination.
"Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?"
Both passages emphasize the importance of self-examination and ensuring one's own life aligns with their professed faith. EGW directly applies this principle to those in ministry.
