"What was the result of the outpouring of the Spirit on the Day of Pentecost? The glad tidings of a risen Saviour were carried to the uttermost parts of the inhabited world. As the disciples proclaimed the message of redeeming grace, hearts yielded to the power of this message. The church beheld converts flocking to her from all directions. Backsliders were reconverted. Sinners united with believers in seeking the pearl of great price. Some who had been the bitterest opponents of the gospel became its champions. The prophecy was fulfilled, “He that is feeble ... shall be as David; and the house of David ... as the angel of the Lord.” Zechariah 12:8 . Every Christian saw in his brother a revelation of divine love and benevolence. One interest prevailed; one subject of emulation swallowed up all others. The ambition of the believers was to reveal the likeness of Christ's character and to labor for the enlargement of His kingdom. AA 48.1"
"In that day shall the Lord defend the inhabitants of Jerusalem; and he that is feeble among them at that day shall be as David; and the house of David shall be as God, as the angel of the Lord before them."
Ellen White directly references Zechariah 12:8 in this passage.
"Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls."
While not a direct quote, the EGW passage describes the results of the outpouring of the Spirit, including conversions and growth of the church, which aligns with the events described in Acts 2:41. The connection is thematic, focusing on the impact of the Spirit's work.
"“With great power gave the apostles witness of the resurrection of the Lord Jesus: and great grace was upon them all.” Acts 4:33 . Under their labors were added to the church chosen men, who, receiving the word of truth, consecrated their lives to the work of giving to others the hope that filled their hearts with peace and joy. They could not be restrained or intimidated by threatenings. The Lord spoke through them, and as they went from place to place, the poor had the gospel preached to them, and miracles of divine grace were wrought. AA 48.2"
"And with great power gave the apostles witness of the resurrection of the Lord Jesus: and great grace was upon them all."
The EGW passage directly quotes Acts 4:33 and expands on the implications of the apostles' powerful witness and the grace that was upon them.
