In 1 Corinthians 16:1-2, Paul wrote, “Now concerning the collection for the saints, as I have given orders to the churches of Galatia, so you must do also: On the first day of the week let each one of you lay something aside, storing up as he may prosper, that there be no collections when I come.”
Nothing is surprising about this text. It relates an obligation that we have to support the Lord’s work in a systemic and regular way. It denotes the Lord’s day as the day when the collection will be taken. We know this to be the day that Christians came together to worship the Lord (cf. Acts 20:7). I states an obligation that we help those in our number (other Christians) who have a physical need (cf. Galatians 6:10).
This is the only place in scripture where there is a pattern established for this financial obligation we as Christians are given toward the Lord’s work. There are other places which give authority to practice benevolence, to support efforts of evangelism and to edify the church, but here alone is the passage that tells us how money is to be gathered in the local church.
What remains is for us to do our duty in a manner that the Holy Spirit prescribes. “So let each one give as he purposes in his heart, not grudgingly or of necessity; for God loves a cheerful giver” (2 Corinthians 9:7).
