A.B. Simpson emphasizes the transformative power of having Jesus dwell within our hearts, enabling us to overcome challenges that we could not face alone. This divine presence becomes our source of power, purity, victory, and joy, shifting our focus from our own abilities to what Christ can accomplish through us. Simpson highlights the Apostle Paul's declaration of strength in Christ, reminding us that we can endure all circumstances through Him. The sermon reassures believers that, despite life's adversities, Christ's victory empowers us to remain pure and steadfast. Ultimately, it is through Jesus that we find true victory over sin and trials.

A precious secret of Christian life is to have Jesus dwelling within the heart and conquering things that we never could overcome. it is the only secret of power in our lives. Men cannot understand it nor will the world believe it, but it is true that God will come to dwell within us and be the power, the purity, the victory and the joy of our lives. Our attitudes will no longer be, "What is the best that I can do?" but we will ask, "What is the best that Christ can do?" it enables us to say with Paul in that beautiful passage in Philippians, I know both how to be abased, and I know how to abound: every where and in all things I am instructed both to be full and to be hungry, both to abound and to stiffer need. I can do all things through Christ which strengtheneth me (4:12-13). With this knowledge I go forth to meet my testings, and this knowledge enables me to stand. I could never keep myself, but because Christ has met the adversary and defeated him for me I am kept pure and clean. Thanks be to God, which giveth us the victory through our Lord Jesus Christ (I Corinthians 15:57).
