Randy Alcorn, Nineteen Questions to Ask Before You Give to Any Organization.
Giving is a great privilege, but also a great responsibility-and sometimes a confusing one. While the biggest hurdle is to gain a vision for giving, and to overcome our reluctance to give, once we've bought into God's call to eternal investment, once we've determined to plunge into giving then we must ask, where and to whom and in what way and for how long should we give? Where should I invest the money God has entrusted to me as his steward, his money manager? How can I tell what's a good place to give to and what isn't?
D. A. Carson, Is Tithing Biblical?
... New Testament ethics turn not so much on legal prescription as on lives joyfully submitted to God.
This is why the most penetrating New Testament passage on giving is 2 Cor. 8–9. Under severe trial, the Corinthians’ "overflowing joy and their extreme poverty welled up in rich generosity" (8:2). Even so, they first gave themselves to the Lord (8:5).
So, why not aim for 20 percent in your giving? Or 30? Or more, depending on your circumstances (8:12)? "For you know the grace of our Lord Jesus Christ, that . . . for your sakes he became poor, so that you through his poverty might become rich" (8:9).
Geoffrey Smith, A Closer Look At The Widow’s Offering: Mark 12:41-44.
The theme of true piety (i.e. confident trust in God) characterizes the remnant in Israel. We are to observe the faith of the widow, who in her devotion to God makes her offering out of her poverty and yet puts “more into the treasury than all the others” ( 12:43 ). The quality of her faith stands in sharp contrast to the false piety of the hypocrites, who are more concerned with appearances than godliness. From her example believers are encouraged to live a life of similar faith, meeting the needs of others while trusting that their heavenly Father, “who sees what is done in secret,” will meet their own needs.

Money is a sensitive issue in our culture. And yet it is central to our commitment to Jesus Christ and a yardstick to measure our understanding of grace.
Explore the wide range of biblical teaching about our heart's attachment to the treasures of this world. Experience why Christian giving is such an adventure. Most of all, renew your heart and change your life, by soaking in the gospel hope which motivates us to live for his glory and to care for others.
