If I'm a blessing to you, then either God will put it on your heart to bless me, or he'll use somebody else to bless me. If I'm friendly with you, then I'll have friends. If I'm merciful with people, the Bible says I'll get mercy back. If I'm not judgmental, then people won't be judgmental with me. And it works also with finances. If you give to help other hurting people and you give to the preaching of the gospel, because you love God, then God takes care of you.
