Prabhupada said in a lecture in 1966 that it is not enough to only believe in God, but we actually have to desire to have an intimate relationship with Him. To believe in God is pious and good, but it is not everything. Generally people come to God and ask, “Please give us this day our daily bread,” or, “O God, please free me from distress.” Prabhupada said that generally people think that God is the order supplier, but actually He is not our order supplier. We must become the order supplier for God. That is devotional service—when God becomes dependent upon us and wants something from us, and we fulfill His requests.
