"But these liberal, wholehearted believers, prompted by a zealous love for the cause and a desire to act promptly, judge themselves capable of doing more than God requires them to do, for their usefulness is crippled in other directions. These willing ones sometimes pledge to raise money when they know not from what source it is coming, and some are placed in distressing circumstances to meet their pledges. Some are obliged to sell their produce at great disadvantage, and some have actually suffered for the conveniences and necessities of life in order to meet their pledges. 3T 410.1"
"For if there be first a willing mind, it is accepted according to that a man hath, and not according to that he hath not."
The EGW passage describes situations where people pledge more than they can afford, leading to hardship. This directly relates to the principle in 2 Corinthians 8:12, which states that giving should be according to what one has, not what one doesn't have. EGW is illustrating the negative consequences of violating this principle.
"There was a time at the commencement of our work when such sacrifice would have been justified, when God would have blessed all who thus ventured out to do for His cause. The friends of truth were few and their means very limited. But the work has been widening and strengthening until there is means enough in the hands of believers to amply sustain the work in all its departments without embarrassing any, if all would bear their proportional part. The cause of God need not be crippled in the slightest degree. The precious truth has been made so plain that many have taken hold of it who have in their hands means which God has entrusted to them to use in advancing the interests of the truth. If these men of means do their duty, there need not be a pressure brought upon the poorer brethren. 3T 410.2"
"Neither was there any among them that lacked: for as many as were possessors of lands or houses sold them, and brought the prices of the things that were sold, And laid them down at the apostles’ feet: and distribution was made unto every man according as he had need."
Both passages discuss the equitable distribution of resources within a religious community to ensure no one lacks. EGW applies this principle to the Seventh-day Adventist church, while Acts describes the early Christian community.
"We are in a world of plenty. If the gifts and offerings were proportionate to the means which each has received of God, there would be no need of urgent calls for means at our large gatherings. I am fully convinced that it is not the best plan to bring a pressure upon the point of means at our camp meetings. Men and women who love the cause of God as they do their lives will pledge upon these occasions, when their families must suffer for the very means that they have promised to give to advance the cause. Our God is not a taskmaster and does not require the poor man to give means to the cause that belongs to his family and that should be used to keep them in comfort and above pinching want. 3T 410.3"
"For I mean not that other men be eased, and ye burdened: But by an equality, that now at this time your abundance may be a supply for their want, that their abundance also may be a supply for your want: that there may be equality:"
Both passages emphasize the principle of equality in giving, where those with abundance should help those in need, and no one should be overburdened to the point of suffering. EGW directly applies this to camp meeting offerings.
