"The disciples began to realize the nature and extent of their work. They were to proclaim to the world the wonderful truths which Christ had entrusted to them. The events of His life, His death and resurrection, the prophecies that pointed to these events, the sacredness of the law of God, the mysteries of the plan of salvation, the power of Jesus for the remission of sins,—to all these things they were witnesses, and they were to make them known to the world. They were to proclaim the gospel of peace and salvation through repentance and the power of the Saviour. DA 805.1"
"But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judea, and in Samaria, and unto the uttermost part of the earth."
Both passages discuss the disciples being witnesses and proclaiming the gospel. The EGW passage expands on the content of their witness, while Acts 1:8 focuses on the power they will receive to do so.
"And he said unto them, Go ye into all the world, and preach the gospel to every creature."
Both passages discuss the disciples' mission to preach the gospel to the world. The EGW passage elaborates on the content of the gospel message.
"“And when He had said this, He breathed on them, and saith unto them, Receive ye the Holy Ghost: Whosesoever sins ye remit, they are remitted unto them; and whosesoever sins ye retain, they are retained.” The Holy Spirit was not yet fully manifested; for Christ had not yet been glorified. The more abundant impartation of the Spirit did not take place till after Christ's ascension. Not until this was received could the disciples fulfill the commission to preach the gospel to the world. But the Spirit was now given for a special purpose. Before the disciples could fulfill their official duties in connection with the church, Christ breathed His Spirit upon them. He was committing to them a most sacred trust, and He desired to impress them with the fact that without the Holy Spirit this work could not be accomplished. DA 805.2"
"And when he had said this, he breathed on them, and saith unto them, Receive ye the Holy Ghost:"
The EGW passage directly quotes and comments on John 20:22.
"(But this spake he of the Spirit, which they that believe on him should receive: for the Holy Ghost was not yet given; because that Jesus was not yet glorified.)"
Both passages discuss the timing of the Holy Spirit's arrival and its connection to Christ's glorification. EGW expands on the idea presented in John 7:39.
"The Holy Spirit is the breath of spiritual life in the soul. The impartation of the Spirit is the impartation of the life of Christ. It imbues the receiver with the attributes of Christ. Only those who are thus taught of God, those who possess the inward working of the Spirit, and in whose life the Christ-life is manifested, are to stand as representative men, to minister in behalf of the church. DA 805.3"
"It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life."
Both passages connect the Spirit with life. EGW's statement that the Holy Spirit is the breath of spiritual life echoes the sentiment in John 6:63 that the Spirit gives life.
"I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me."
Both passages discuss the idea of Christ living in the believer. EGW's statement that the impartation of the Spirit imbues the receiver with the attributes of Christ is thematically similar to Paul's statement in Galatians 2:20 that he lives, yet not he, but Christ lives in him.
"Galatians 5:21 . If they persist in sin, the judgment you have declared from God's word is pronounced upon them in heaven. In choosing to sin, they disown Christ; the church must show that she does not sanction their deeds, or she herself dishonors her Lord. She must say about sin what God says about it. She must deal with it as God directs, and her action is ratified in heaven. He who despises the authority of the church despises the authority of Christ Himself. DA 805.4"
"Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God."
Ellen White directly references Galatians 5:21 in this passage.
"Verily I say unto you, Whatsoever ye shall bind on earth shall be bound in heaven: and whatsoever ye shall loose on earth shall be loosed in heaven."
EGW's passage directly relates the church's actions on earth to their ratification in heaven, which is the core principle of Matthew 18:18. She applies this principle to the context of dealing with sin within the church.
