I believe the Our Father is an actual prayer and not just a model for prayer. I do agree that inner conversations with God could be considered prayer. I recite written prayers as well as my own prayers and most of these prayers are not in the bible, especially my personal prayers
Please do not misunderstand the 'prophesy' friend. What beloved VCO, who is for all of us, 'testify' that they are 'actual initial prayer' and also a 'model of prayer among others'.
Please reread the Holy Scripture in 'context' and 'listen and pat attention' to what JESUS said in the beginning to HIS disciples and then gave them the 'actual prayer', that it is also a 'model of prayer' among many given to them and the church written in the New Covenant/Testament.
GOD bless you in the name of LORD JESUS CHRIST.
