Here is another great website to add to your resource list: Eternal Perspectives by Randy Alcorn. This website includes a wealth of articles and audio/video teachings on a wide variety of topics that I think will be a great encouragement to you. I first heard Randy speak at a pastor's conference several years ago and was very impressed with his insights on money and ministry. His book the Treasure Principle is a one-sitting, easy-to-read classic that has radically changed the outlook of many Christians (myself included). Here are some of my favorite quotes from this book:
Our giving is a reflexive response to the grace of God in our lives. It doesn't come out of our altruism or philanthropy—it comes out of the transforming work of Christ in us. This grace is the action; our giving is the reaction. We give because He first gave to us. The greatest passage on giving in all Scripture ends not with "Congratulations for your generosity," but "Thanks be to God for his indescribable gift!" (2 Corinthians 9:15) [Page 30]
As thunder follows lightning, giving follows grace When God's grace touches you, you can't help but respond with generous giving. [Pages 33-34]
Jesus said, "Where your treasure is, there your heart will be also" (Matthew 6:21). That's the second key to the Treasure Principle. By telling us that our hearts follow our treasure, Jesus is saying, "Show me your checkbook, your VISA statement, and your receipts, and I'll show you where your heart is." Suppose you buy shares of General Motors. What happens? You suddenly develop interest in GM. You check the financial pages. You see a magazine article about GM and read every word, even though a month ago you would have passed right over it. Suppose you're giving to help African children with AIDS. When you see an article on the subject, you're hooked. If you're sending money to plant churches in India and an earthquake hits India, you watch the news and fervently pray. As surely as the compass needle follows north, your heart will follow your treasure. Money leads; hearts follow. [Pages 41-42]
There are many roadblocks to giving: unbelief, insecurity, pride, idolatry, desire for power and control. The raging current of our culture—and often our churches—makes it hard to swim upstream. It's considered "normal" to keep far more than we give. But I'm convinced that the greatest deterrent to giving is this: the illusion that earth is our home. [Page 44]
