"Return to Michigan and California We returned to Michigan, and after a few days went to Lansing to attend the camp meeting there, which continued two weeks. Here I labored very earnestly, and was sustained by the Spirit of the Lord. I was greatly blessed in speaking to the students, and in laboring for their salvation. This was a remarkable meeting. The Spirit of God was present from the beginning to the close. As the result of the meeting, one hundred and thirty were baptized. A large part of these were students from our College. We were rejoiced to see the salvation of God in this meeting. After spending a few weeks in Battle Creek, we decided to cross the plains to California. LS 228"
"Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls."
Both passages describe baptisms following the reception of a message. However, the scale and context are vastly different, reducing the confidence.
"This meeting was of especial benefit to the cause in Vermont. The Lord gave me strength to speak to the people as often as once each day. LS 228.1"
"And with great power gave the apostles witness of the resurrection of the Lord Jesus: and great grace was upon them all."
Both passages describe being given strength to speak and witness. The connection is valid, though not a direct quote or allusion.
"We went directly from Vermont to the New York camp meeting. The Lord gave me great freedom in speaking to the people. But some were not prepared to be benefited by the meeting. They failed to realize their condition, and did not seek the Lord earnestly, confessing their backslidings and putting away their sins. One of the great objects of holding camp meetings is that our brethren may feel their danger of being overcharged with the cares of this life. A great loss is sustained when these privileges are not improved. LS 228.2"
"For this people’s heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, and I should heal them."
The EGW passage speaks of people not being prepared to be benefited, failing to realize their condition and seek the Lord. This aligns with Matthew 13:15, which describes people whose hearts are hardened and unwilling to see, hear, and understand.
