Some feel their need of the atonement, and with the recognition of this need, and the desire for a change of heart, a struggle begins. To renounce their own will, perhaps their chosen objects of affection or pursuit, requires an effort, at which many hesitate and falter and turn back. Yet this battle must be fought by every heart that is truly converted. We must war against temptations without and within. We must gain the victory over self, crucify the affections and lusts; and then begins the union of the soul with Christ. As the dry and apparently lifeless branch is grafted into the living tree, so may we become living branches of the True Vine. And the fruit which was borne by Christ will be borne by all His followers. After this union is formed, it can be preserved only by continual, earnest, painstaking effort. Christ exercises His power to preserve and guard this sacred tie, and the dependent, helpless sinner must act his part with untiring energy, or Satan by his cruel, cunning …
"And they that are Christ’s have crucified the flesh with the affections and lusts."
Both passages discuss crucifying the flesh with its affections and lusts. EGW elaborates on the struggle involved in renouncing one's will and affections, which aligns with the concept of crucifying the flesh in Galatians 5:24.
"Every Christian must stand on guard continually, watching every avenue of the soul where Satan might find access. He must pray for divine help and at the same time resolutely resist every inclination to sin. By courage, by faith, by persevering toil, he can conquer. But let him remember that to gain the victory Christ must abide in him and he in Christ. 5T 47.2"
"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 resistance against temptation. 1 Peter 5:8 warns about the devil seeking to devour, while EGW stresses the importance of guarding the soul and resisting sin. The connection is thematic and focuses on spiritual warfare.
