"We were in much perplexity. Must we be driven from the work by bodily infirmities? Would Satan be permitted to exercise his power upon us, and contend for our usefulness and lives, as long as we should remain in the world? We knew that God could limit the power of Satan. He might suffer us to be tried in the furnace, but would bring us forth purified and better fitted for His work. LS 148.2"
"Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:"
The EGW passage directly mentions Satan's opposition and the need for vigilance, mirroring the warning in 1 Peter 5:8 about the devil seeking to devour.
"I went into a log house near by, and there poured out my soul before God in prayer that He would rebuke the disease and strengthen my husband to endure the journey. The case was urgent, and my faith firmly grasped the promises of God. I there obtained the evidence that if we should proceed on our journey to Michigan, the angel of God would go with us. When I related to my husband the exercise of my mind, he said that his own mind had been exercised in a similar manner, and we decided to go, trusting in the Lord. My husband was so weak that he could not buckle the straps to his valise, and called Brother Cottrell to do it for him. LS 148.3"
"Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much."
The EGW passage describes Ellen White praying for her husband's healing and strength, and receiving assurance that God would be with them. This aligns with the theme of James 5:16 regarding the power of prayer for healing and the effectiveness of fervent prayer.
