Prayer is the active effort of a person to communicate with a higher power, a deity, or a spirit. It is a spiritual practice that we encounter in various forms from ancient times in all religions and traditions.

Prayer can be either individual or communal. It can involve the use of words, hymns, or psalms, or it can be done in complete silence. According to Christian tradition, prayer is the conversation of humans with God, which can take various forms.

When we invoke God for help, this prayer is called supplication or petition. If our prayer is to thank God, it is called thanksgiving. Finally, there is also doxology, which is the prayer made to glorify the greatness and omnipotence of God.
