He also commended the widow who gave essentially nothing in actual material value, because she gave "all she had" (Luke 21:4). giving" issue is the change from the Old Testament Sabbath to the new covenant concept of Sunday as the "Lord's Day." Are Christians required to keep the specific, technical, negative restrictions of the Old Testament Sabbath (such as the restrictions against work, travel, trade, etc.)? But those same evangelicals do believe in the concept of Sunday as the "Lord's Day," on which most or all of the day should be spent positively pursuing the means of grace, rest and the other things of God out of love for Him (gathering with the saints in fellowship and worship, reading, discussing and listening to the preaching of God's Word, the Lord's Supper, etc.) and for the sake of His glory and His people.
As with giving, the idea is that in light of the new covenant of grace and our love for Christ, we are not under the restrictions or requirements of the Old Testament law, but neither should we be of ourselves to Gospel work and the things of God.
In more than one of his letters, the apostle Paul instructs Christians to give financially — robustly and even sacrificially — to the work of the Gospel, especially toward the preaching of the Word (see, for example, 1 Corinthians 9:3-15, 2 Corinthians 5-9 and 1 Timothy -18).I am in no way advocating a descent into legalism here; I'm merely suggesting that as we consider this issue of how much to give, we start by giving some thought to the definitions of "poverty" and "abundance." This is a complex issue, and obviously what I've written here is not enough to cover it fully.
