We respond to God through giving.
An equally important part of the worship service is the time of corporate offering. The offering is giving back to God from what he has given to us. Its roots are found in the Old Testament worship of God as well as in the New Testament life of the church.
Ascribe to the LORD the glory due His name;
Bring an offering, and come before Him;
Worship the LORD in holy array.
The offering should not be regarded as simply a time to raise the money needed to run the church, nor should it should become a time of brow-beating and manipulation. It is a time of worship during which the church body responds to God by giving to the body of Christ. The offering is taken, not with great fanfare, but with a sense of humble and thankful worship.
Many churches today have stopped taking a public offering, choosing instead to place offering boxes in various locations around the place where the church meets. This has the potential of robbing the people of God of the corporate worship of giving in unison. A church would be wise to consider ways in which they can make it clear that the offering is not for visitors, but for the people of the church, while stressing that participation in the offering is an act of grateful and obedient worship.
 Some have done this in order to not offend visitors who believe that “Churches just want your money.” Others have done this to maintain secrecy in giving, claiming Matthews 6:3-4 as a basis. Neither of these reasons seem convincing to this author.
