"Let the worker show his growth in grace by submission to the will of God. Thus he will gain a rich experience. As in faith he receives, believes, and obeys Christ's words, there will be an intensity of effort; there will be cherished a faith that works by love and purifies the soul. The fruit of the Spirit will be seen in the life, and the efficiency of the Spirit will be seen in the work. 7T 38.5"
"For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love."
EGW directly quotes the phrase 'faith which worketh by love' from Galatians 5:6, making this an explicit allusion.
"But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, Meekness, temperance: against such there is no law."
EGW uses the phrase 'fruit of the Spirit' which is a direct reference to Galatians 5:22-23. She connects the idea of the fruit of the Spirit being seen in the life of the worker, which aligns with the biblical passage.
"Seeing ye have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren, see that ye love one another with a pure heart fervently:"
Both passages connect obedience to truth with the purification of the soul and the development of love. While not a direct quote, the thematic overlap is significant.
