It is often my study at home. It is also a little country road in Pennsylvania, where I sometimes retreat to be with the Lord. It is walking the streets in New York City. A few weeks ago it was a Florida beach, where I walked for hours, shut in with God. Jesus warned against hypocrisy in prayer.
Hypocrites are actors - people who act holy to receive the praises of others.
Our flesh loves to be applauded and complimented. Yet the flesh can be seen at work in us when we do things for God but can't understand why others don't appreciate it. They do not shut themselves up in prayer, alone with their Father. I remember hearing about one pastor's reputation as a man of prayer. He must be some preacher.
