Have you ever been around a person shouting and proclaiming to be so spiritual? But there's something about them that isn't quite right? God just doesn't seem to be anywhere around them. It is the strangest sense of empty. No warmth. I imagine Jesus encountered this with the Rabbi's and the hierarchy in the Synagogues of his day. Everyone seemed to be going through the motions of honoring "God" but their heart just wasn't in it. That unconditional giving just wasn't their. You see evidence of the total disregard for God when Jesus goes completely off in the temple. How dare these people allow commerce and trade? Selling and barginning in the house of the Lord? This very thing goes on in some of the Mega churches of today. We have to be aware of the wolf in sheeps clothing. The hypocrite.
Matthew 7:5 You hypocrite, first take the log out of your own eye, and then you will see clearly to take the speck out of your brother's eye.
Matthew 23: 13-15 But woe to you, scribes and Pharisees, hypocrites! For you shut the kingdom of heaven in people's faces. For you neither enter yourselves nor allow those who would enter to go in. Woe to you, scribes and Pharisees, hypocrites! For you travel across sea and land to make a single proselyte, and when he becomes a proselyte, you make him twice as much a child of hell as yourselves.
