"These words are full of instruction, and strike the keynote of victory. The apostle presents before the believers the ladder of Christian progress, every step of which represents advancement in the knowledge of God, and in the climbing of which there is to be no standstill. Faith, virtue, knowledge, temperance, patience, godliness, brotherly kindness, and charity are the rounds of the ladder. We are saved by climbing round after round, mounting step after step, to the height of Christ's ideal for us. Thus He is made unto us wisdom, and righteousness, and sanctification, and redemption. AA 530.1"
"But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption:"
EGW directly connects the 'ladder of Christian progress' to the idea of Christ being made unto us wisdom, righteousness, sanctification, and redemption. This echoes the sentiment in 1 Corinthians 1:30, where Christ is explicitly stated to be these things. The connection is strong and meaningful.
"I press toward the mark for the prize of the high calling of God in Christ Jesus."
Both passages discuss pressing forward in the Christian life. EGW uses the metaphor of climbing a ladder, while Philippians 3:14 speaks of pressing toward the mark. The underlying theme of striving for a higher goal in Christ is present in both.
"God has called His people to glory and virtue, and these will be manifest in the lives of all who are truly connected with Him. Having become partakers of the heavenly gift, they are to go on unto perfection, being “kept by the power of God through faith.” 1 Peter 1:5 . It is the glory of God to give His virtue to His children. He desires to see men and women reaching the highest standard; and when by faith they lay hold of the power of Christ, when they plead His unfailing promises, and claim them as their own, when with an importunity that will not be denied they seek for the power of the Holy Spirit, they will be made complete in Him. AA 530.2"
"Who are kept by the power of God through faith unto salvation ready to be revealed in the last time."
Ellen White directly references 1 Peter 1:5 in this passage.
"Having received the faith of the gospel, the next work of the believer is to add to his character virtue, and thus cleanse the heart and prepare the mind for the reception of the knowledge of God. This knowledge is the foundation of all true education and of all true service. It is the only real safeguard against temptation; and it is this alone that can make one like God in character. Through the knowledge of God and of His Son Jesus Christ, are given to the believer “all things that pertain unto life and godliness.” No good gift is withheld from him who sincerely desires to obtain the righteousness of God. AA 530.3"
"And beside this, giving all diligence, add to your faith virtue; and to virtue knowledge; And to knowledge temperance; and to temperance patience; and to patience godliness; And to godliness brotherly kindness; and to brotherly kindness charity."
Both passages discuss adding virtues to one's faith. EGW focuses on virtue leading to knowledge of God, while Peter lists a sequence of virtues. The connection is thematic and reflects a shared emphasis on spiritual growth.
