"The Work That Requires Our Thought Wrongs cannot be righted, nor can reformations in conduct be made by a few feeble, intermittent efforts. Character building is the work, not of a day, nor of a year, but of a lifetime. The struggle for conquest over self, for holiness and heaven, is a lifelong struggle. Without continual effort and constant activity, there can be no advancement in the divine life, no attainment of the victor's crown. MH 452"
"I press toward the mark for the prize of the high calling of God in Christ Jesus."
Both passages emphasize the continuous effort required in the Christian life and striving towards a goal (holiness/heaven or the prize of the high calling).
"The strongest evidence of man's fall from a higher state is the fact that it costs so much to return. The way of return can be gained only by hard fighting, inch by inch, hour by hour. In one moment, by a hasty, unguarded act, we may place ourselves in the power of evil; but it requires more than a moment to break the fetters and attain to a holier life. The purpose may be formed, the work begun; but its accomplishment will require toil, time, perseverance, patience, and sacrifice. MH 452.2"
"For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would."
Both passages discuss the struggle between the flesh and the spirit, and the difficulty of overcoming sinful tendencies. EGW elaborates on the effort required to return to a higher state, echoing the sentiment of the internal conflict described in Galatians.
"We cannot allow ourselves to act from impulse. We cannot be off guard for a moment. Beset with temptations without number, we must resist firmly or be conquered. Should we come to the close of life with our work undone, it would be an eternal loss. MH 452.3"
"Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:"
Both passages emphasize the need for vigilance and self-control in the face of temptation. EGW's warning against acting from impulse and being off guard directly reflects the principle of being sober and vigilant as warned in 1 Peter.
"The life of the apostle Paul was a constant conflict with self. He said, “I die daily.” 1 Corinthians 15:31 . His will and his desires every day conflicted with duty and the will of God. Instead of following inclination, he did God's will, however crucifying to his nature. MH 452.4"
"I protest by your rejoicing which I have in Christ Jesus our Lord, I die daily."
Ellen White directly references 1 Corinthians 15:31 in this passage.
"For I delight in the law of God after the inward man: But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members."
Both passages describe the internal conflict between one's desires and the will of God. EGW uses Paul as an example, referencing his statement "I die daily," which illustrates the constant struggle against self, similar to the warring laws described in Romans 7.
