How careful we need to be about the sin of hypocrisy. It is a sin that involves wearing a mask, pretending to be what we are not. We cannot commit this sin without trying to bind the eyes of the Lord also. But he knows all that we know and far more. We cannot come into the house of God with known sin unrepented of, or our worship will be rejected by God. We can bring our sins to him on a daily basis, but we cannot pretend that they are not sins.
Do we put ourselves first, and the Lord last? Israel was taught to do the opposite in their offerings and sacrifices. They were to bring the firstfruits of their fields to the Lord (Leviticus 2:14); they were to bring animals that were without defect (Exodus 12:5); and it was their firstborn that belonged to the Lord (Exodus 13:15). Do we give the Lord what remains over after we have taken all we want, both in terms of energy and time and possessions?
