Although all prayers are warfare in the sense that it opposes the kingdom of darkness, the term “Prayer Warfare” nevertheless carries a heavy meaning of prayer that goes beyond just talking to God. It’s specified in a distinct category where you are engaged in live and direct combat with demonic forces from the land, sea or air.
It is simply an act of warfare, where we stand in authority and oppose the demonic operations of the kingdom of darkness through praying, declarations etc.
it is talking to God about situations, whether it’s your situation or the situation of someone else. This can be done while walking, resting, washing, cleaning etc.
Prayer can denote a direct petition or short, sharp cry of the heart in its distress (Psa 30:2; Php 1:9 ), or prayer can be long as in (1 Kings 8:22-53) or can be in a praise form like that of Hannah (1Sa 2:1-10) and (Jeremiah 31:7), or Petition for benefits either for one’s self or can be intercession -petition for others as in that of Jesus, Paul and Solomon (John 17, Eph 3:14-21, 1Kings 8:22-53).
