3But when you give to the needy, do not let your left hand know what your right hand is doing, 4so that your giving may be in secret. Then your Father, who sees what is done in secret, will reward you. - Matthew 6:3-4Jesus is encouraging us to allow giving to be so much about God and also so common in our lives that it becomes second nature. Remember our second nature is who we are when we live by the Spirit and not by the flesh. It is who we are because we have been radically changed by the grace and presence of Christ. Where we don’t even think about keeping track of what, how often, or how much we give. We don't add it up in our minds so that we become proud of our own generosity.
We shouldn’t keep the account. God does that. He sees everything and He records it all. And, do you know what he will do? He will reward us.
