Luke 11:38 - "And when the Pharisee saw it, he marvelled that he had not first washed before dinner."
LUKE 11:37-41
A sure sign of the error of legalism is misplaced priorities, as we see here with these Pharisees. It is not recorded in Scripture that the Pharisees marveled at the wonderful works of Jesus. They were too busy looking for something to criticize (Mark 3:2). But they marveled at Jesus not washing His hands. This is a classic example of straining out a gnat and swallowing a camel (Mt. 23:24).
Those who seek to earn righteousness through keeping the Law are consumed with "doing," while those who receive righteousness by faith are simply confessing what has already been done. This is a simple and yet profound difference. If we are still "doing" acts of holiness to get God to move in our lives, then we are still operating under a "Law" mentality that is not faith (Gal. 3:12). When we simply believe and confess what has already been provided through Christ, that's grace.
