For Christian prayer stands the promise, which Jesus the Lord gave to his disciples: “And I will do whatever you ask in my name, so that the Father may be glorified in the Son. You may ask me for anything in my name, and I will do it.” (John 14:13-14)

In prayer we address God with trust. Whoever prays is calling God and enters into conversation with Him. In the life of Christians, prayer is apparently the most important tool of grace. The opportunity to pray is the greatest advantage of believers: “a beautiful tool of grace, the possibility to approach to God, all others tools of grace are useful in so far as they are connected with prayer or they are preparing for it.”

Through prayer "the Spirit himself testifies with our spirit that we are God’s children.” (comp. Rom 8,16) The Holy Spirit makes our prayers possible. “In the same way, the Spirit helps us in our weakness. We do not know what we ought to pray for, but the Spirit himself intercedes for us through wordless groans.” (comp. Rom 8,26)
We can pray in various ways. The prayer can be personal, quiet, but also delivered aloud, for instance in family or in a small community. Public prayer within liturgy makes possible for a congregation to speak with God and listen to God together. During worship the prayer can be led by a preacher or a layman. To the standard interceding prayer can be added the personal pleads and intercessions (quiet or loud) of other worship participants.

Personal prayer can be expressed through psalms, the Lord’s Prayer, prayers of church fathers, written or spontaneous prayers. Meditation, silence or contemplation, is also form of prayer.
