I also think that God cares deeply about our giving. Secondly, God wants us to have abundant life. Jesus wants us to have an abundant life now. Abundant means more than having stuff and money. Abundant means having hope and joy and the only way it happens is when we give of ourselves in the service of others and in the name of Jesus.
Generous givers understand what abundant living is all about.
God wants us to be able to share in the abundant life right now. Yes, God knows about our giving and cares about our giving. Jesus, watching the widow at the treasury took note of how we give, why we give and how much we give. The good news is that there is a principle of great equality in our giving. There is nothing unreasonable about that standard.
