A pastor once said that the greatest message he ever preached, was in the car between his house and the church. The greatest time of revival he has experienced is in the bathroom when he was singing worship songs in the shower. In otherwords, the best time of personal revival can be those unplanned times when you are alone with the Lord. I believe that because I know the Lord loves those personal times with him. Although,we need to set apart time to meet with God; but sometimes the best time to meet with God are those spontaneous times in His presence. What do you think?
