Prayer is elevating the mind to the Almighty God and confiding with Him in spiritual utterances. Through prayer we worship and thank Him and lay before Him our needs.
Prayer is not only an obligatory duty, but the first and the most beneficial one. We were lead to it by natural instinct which guided us to approach our God, may He be exalted. Moreover, God instructed us regarding prayer through children of Israel. He taught them the principles of His worship in the elementary school of prophets until the time came when He sent His beloved Son, the Divine Teacher, who taught the world the perfect Law and true worship.
The effect of prayer is really mighty, as the Apostle points out: “Great is the power of prayer of a righteous man” (James 5:16), especially the perfect prayer of spiritual elders through which they receive divine gifts and see miraculous visions.
