Before you pray, bow quietly before God, just to remember and realize who He is, how near He is, how certainly He can and will help. Just be still before Him, and allow His Holy Spirit to waken and stir up in your soul the child-like disposition of absolute dependence and confident expectation. Wait upon God as a Living Being, as the Living God, who notices you, and is just longing to fill you with His salvation. Wait on God till you know you have met Him; prayer will then become so different.
And when you are praying, let there be intervals of silence, reverent stillness of soul, in which you yield yourself to God, in case He may have aught He wishes to teach you or to work in you. Waiting on Him will become the most blessed part of prayer, and the blessing thus obtained will be doubly precious as the fruit or such fellowship with the Holy One, God has so ordained it, in harmony with His holy nature, and with ours, that waiting on Him should be the honor we give Him. Let us bring Him the service gladly and truthfully; He will reward it abundantly.
