The gospel-driven thought for today:
All attempts at holiness which are not rooted in the gospel produce fruit of self-righteousness and legalism.
This was the case with the Pharisees who, in attempting to establish and maintain national holiness after the exile, did so without reference to the covenant faithfulness of God.
If their attempts at holiness had been rooted in this, the righteousness of God that comes by faith instead of works, surely all self-righteous pride as reflected in the lives of the Pharisees in the N.T. would not exist at all.
Rather, we would see a humility befitting those who are sinners and know it.
