The thought James captures here is repeated over and over again in the Bible. Everything good we have is from God. He loves to give. He loves to bless. He loves to show us generosity time and again. And He desires that we grow into His image and reflect His love. That is why God wants us to give to the ministry of His church. God can do anything He wants to without our help. But He commands us to give so that we will grow in our imitation of His own generosity.
