Prayer acknowledges the presence of God. By prayer, one acknowledges God's power and goodness, and one's own neediness and dependence.
Prayer can be divided into vocal and mental types. Vocal prayer is that which is made by using some approved form of words, read or recited Common vocal prayers include the Lord's Prayer, the Hail Mary, the Glory Be and the Apostles' Creed. However, a vocal prayer can be a simple request such as “God help me!” or “Thank you God.”
Mental prayer is that which is made without employing either words or formulas of any kind. It is a form of prayer whereby one loves God through dialogue with him, meditating on his words, and contemplating him.The tradition of the Roman Catholic Church highlights four basic elements of prayer: Prayer of Blessing and Adoration, Prayer of Petition, Prayer of Intercession, and Prayer of Thanksgiving.
The important thing to remember is that God wants to hear from us and commune with us through prayer.
