Chapter Twenty-Nine of Pastor Rob's book, "Enjoying the Goodness of God" read by the author. The principle of sowing and reaping is true and real. But it has nothing to do with grace, it is completely based on works. But new testament giving should be the fruit of receiving the grace of God, not just a principle to be worked. Giving should be an outflow of what God is doing in us, not what we are doing for God.
