"And the same compassion that reached out to rescue Peter is extended to every soul who has fallen under temptation. It is Satan's special device to lead man into sin, and then leave him, helpless and trembling, fearing to seek for pardon. But why should we fear, when God has said, “Let him take hold of My strength, that he may make peace with Me; and he shall make peace with Me”? Isaiah 27:5 . Every provision has been made for our infirmities, every encouragement offered us to come to Christ. COL 156.1"
"Or let him take hold of my strength, that he may make peace with me; and he shall make peace with me."
EGW directly quotes Isaiah 27:5, making it a clear and intentional reference.
"Christ offered up His broken body to purchase back God's heritage, to give man another trial. “Wherefore He is able also to save them to the uttermost that come unto God by Him, seeing He ever liveth to make intercession for them.” Hebrews 7:25 . By His spotless life, His obedience, His death on the cross of Calvary, Christ interceded for the lost race. And now, not as a mere petitioner does the Captain of our salvation intercede for us, but as a Conqueror claiming His victory. His offering is complete, and as our Intercessor He executes His self-appointed work, holding before God the censer containing His own spotless merits and the prayers, confessions, and thanksgiving of His people. Perfumed with the fragrance of His righteousness, these ascend to God as a sweet savor. The offering is wholly acceptable, and pardon covers all transgression. COL 156.2"
"Wherefore he is able also to save them to the uttermost that come unto God by him, seeing he ever liveth to make intercession for them."
EGW directly quotes Hebrews 7:25.
"My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:"
Both passages discuss Jesus as an advocate/intercessor. The connection is strong enough to confirm.
