If you were guaranteed a meeting place with the infinite God, how often would you go there? If you could look into His face and call Him Father and know that He has promised to reward your requests openly, how long would you stay? Do you have an "inner chamber?" A place where you long to go and love to stay - a place designated as the "classroom" where Christ teaches you to pray? 

"As long as in our worship of God we are chiefly occupied with our own thoughts and exercises, we shall not meet Him who is a Spirit, the unseen One. But to the man who withdraws himself from all that is of the world and man, and prepares to wait upon God alone, the Father will reveal Himself." - Andrew Murray
