Rewards in the Christian life are tricky.  We want our good works to be genuine, not false.  We want to do good because it is good, not because we are bribed.  And yet, Jesus unapologetically tells us to expect rewards in heaven for our obedience on earth.  He even tells us to give to the needy so that we might “Provide yourselves with moneybags that do not grow old, with a treasure in the heavens that does not fail, where no thief approaches and no moth destroys” (Luke 12:33).  Did you know that your generosity is an investment in heaven with guaranteed returns?  This is no earthly bribe.  It is heavenly sanity.
