6:8. In contrast to the Gentile’s fear of not being heard, Jesus assures his followers that God as Father is fully aware of the needs of his children. Prayer, then, is not so much an effort to inform God on matters of which he is ignorant, as it is an expression of our confidence in God. It is an act of worship whereby we acknowledge his presence, and in intimate familiarity and trust we lift our petitions to a loving Father. The efficacy of prayer is therefore not grounded in technique or formulas
