"Great objects are accomplished by this system. If one and all would accept it, each would be made a vigilant and faithful treasurer for God, and there would be no want of means with which to carry forward the great work of sounding the last message of warning to the world. The treasury will be full if all adopt this system, and the contributors will not be left the poorer. Through every investment made they will become more wedded to the cause of present truth. They will be “laying up in store for themselves a good foundation against the time to come, that they may lay hold on eternal life.” 3T 389.1"
"Laying up in store for themselves a good foundation against the time to come, that they may lay hold on eternal life."
EGW directly quotes 1 Timothy 6:19, making it a clear and explicit allusion.
"As the persevering, systematic workers see that the tendency of their benevolent efforts is to nourish love to God and their fellow men, and that their personal efforts are extending their sphere of usefulness, they will realize that it is a great blessing to be co-workers with Christ. The Christian church, as a general thing, are disowning the claims of God upon them to give alms of the things which they possess to support the warfare against the moral darkness which is flooding the world. Never can the work of God advance as it should until the followers of Christ become active, zealous workers. 3T 389.2"
"For we are labourers together with God: ye are God’s husbandry, ye are God’s building."
Both passages discuss working together with God. EGW emphasizes benevolence and usefulness, while 1 Corinthians 3:9 speaks of being laborers together with God.
