The Qualities of God

Obviously, there are set prayers, but there are personal prayers too. 

You have not accomplished anything if you think like this, "God I did my prayer rule, now give me something because I have done my duty." 

He who prays only when he prays is not praying. Therefore, prayer must spring forth from the heart.

Prayer is literally our life now and forever. 

Look mother the sheep is pawing the ground with its hoof before going to sleep. Why is it paying? And my mother said, "It is worshipping." 

When the father leads the charge against spiritual attacks the whole family wins.
