"Men and women professing godliness and expecting translation to heaven without seeing death, I warn you to be less greedy of gain, less self-caring. Redeem your godlike manhood, your noble womanhood, by noble acts of disinterested benevolence. Heartily despise your former avaricious spirit and regain true nobility of soul. From what God has shown me, unless you zealously repent, Christ will spew you out of His mouth. Sabbathkeeping Adventists profess to be followers of Christ, but the works of many of them belie their profession. “Ye shall know them by their fruits.” “Not everyone that saith unto Me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of My Father which is in heaven.” 1T 482.1"
"Wherefore by their fruits ye shall know them."
EGW directly quotes Matthew 7:20.
"So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of my mouth."
EGW alludes to the concept of being 'spewed out' which is directly from Revelation 3:16.
I appeal to all who profess to believe the truth, to consider the character and life of the Son of God. He is our example. His life was marked with disinterested benevolence. He was ever touched with human woe. He went about doing good. There was not one selfish act in all His life. His love for the fallen race, His desire to save them, was so great that He took upon Himself the wrath of His Father, and consented to suffer the penalty of that transgression which plunged guilty man in degradation. He bore the sins of man in His own body. “He hath made Him to be sin for us, who knew no sin; that we might be made the righteousness of God in Him.” 1T 482.2 True generosity is too frequently destroyed by prosperity and riches. Men and women in adversity or in humble poverty will sometimes express very great love for the truth and special interest for the prosperity of the cause of God and for the salvation of their fellow men, and will tell what they would do if they only had the means. God …
"For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him."
The EGW passage directly quotes 2 Corinthians 5:21.
"How God anointed Jesus of Nazareth with the Holy Ghost and with power: who went about doing good, and healing all that were oppressed of the devil; for God was with him."
The EGW passage directly quotes and elaborates on the idea of Jesus 'going about doing good' from Acts 10:38.
