"But regarding this proposed camp meeting it seemed impossible to arouse much enthusiasm. Logging camps, and groups of tents for road builders, were well-known institutions, not much to be desired; but a comfortable camp for a company of people gathered to worship God, was an entirely new thing for New Zealand. LS 342.1"
"But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned."
The verse and the EGW quote both deal with a lack of understanding or appreciation for spiritual things. The people in New Zealand didn't understand the concept of a camp meeting for worship, similar to how the 'natural man' doesn't understand the things of the Spirit.
"On account of the financial depression, it was unusually difficult for many to attend. Up to the beginning of the meeting, there was little promise that more than thirty would be encamped on the grounds. For that number tents were provided. But just as the meeting was opening, the people from the different churches came in, unannounced, until there were twice as many as had been expected. During the last week of the meeting there were eighteen tents in the encampment, occupied by fifty-three persons. Many others occupied rooms near by. These, with the membership of the Napier church, made a good sized congregation during the day. Every evening the large tent was well filled. LS 342.2"
"But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you."
The EGW passage describes how, despite initial doubts and financial difficulties, more people than expected attended the camp meeting. This echoes the principle in Matthew 6:33 that seeking God's kingdom first results in other needs being met. The unexpected attendance can be seen as a blessing added after prioritizing spiritual matters.
"As the meeting progressed, the camp meeting plan was heartily approved, and it was voted that the next annual conference be held in camp. Resolutions were adopted endorsing the Australasian Bible School, and funds were contributed,—five hundred dollars for the furniture, and four hundred dollars as a students’ aid fund. Two hundred and seventy dollars was subscribed as a camp meeting fund. LS 342.3"
"And they continued stedfastly in the apostles’ doctrine and fellowship, and in breaking of bread, and in prayers."
Both passages describe a community of believers engaging in activities related to their faith. Acts 2:42 highlights doctrine, fellowship, and prayer, while the EGW passage describes approving plans, endorsing a school, and contributing funds. The common thread is the active participation and support within a religious community.
