When you stand up in prayer, it is necessary for you to have firm faith that your God has power over all things. Only then will your prayer be accepted and you will behold the wonders of God’s power that we have beheld. Our testimony is based on observation and not on hearsay. How should the supplication of a person be accepted and how should he have the courage to pray at times of great difficulty, when according to him he is opposed by the law of nature, unless he believes that God has power over everything? O fortunate ones, follow not these practices. Your God is One who holds aloft innumerable stars without the use of columns and who has created heaven and earth from nothing. Then would you think so ill of Him as to imagine that your objective is beyond His power? Such ill-thinking will frustrate you.
