"The apostle Peter had had a long experience in the things of God. His faith in God's power to save had strengthened with the years, until he had proved beyond question that there is no possibility of failure before the one who, advancing by faith, ascends round by round, ever upward and onward, to the topmost round of the ladder that reaches even to the portals of heaven. AA 533.1"
"Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God."
The EGW passage speaks of ascending 'round by round' to the portals of heaven, emphasizing faith and perseverance. Hebrews 12:2 encourages looking unto Jesus, the author and finisher of our faith, who endured the cross. Both passages highlight faith and perseverance in the Christian journey, though the imagery is different.
"For many years Peter had been urging upon the believers the necessity of a constant growth in grace and in a knowledge of the truth; and now, knowing that soon he would be called to suffer martyrdom for his faith, he once more drew attention to the precious privileges within the reach of every believer. In the full assurance of his faith the aged disciple exhorted his brethren to steadfastness of purpose in the Christian life. “Give diligence,” he pleaded, “to make your calling and election sure: for if ye do these things, ye shall never fall: for so an entrance shall be ministered unto you abundantly into the everlasting kingdom of our Lord and Saviour Jesus Christ.” Precious assurance! Glorious is the hope before the believer as he advances by faith toward the heights of Christian perfection! AA 533.2"
"Wherefore the rather, brethren, give diligence to make your calling and election sure: for if ye do these things, ye shall never fall:"
The EGW passage directly quotes 2 Peter 1:10 and elaborates on its meaning.
