"Your Bible version is misleading you into false theology"
No, my bible is correct theology. The Lord's Prayer was taught to His disciples later in His ministry when the disciples had been called and again after they had been commissioned and sent out to minister. They were already sons of God so could call God, Father. No one can call God, Father unless given the authority by the Father dependant upon their believing that Jesus is the Christ, not by forgiving some one else.
Good grief! I would hope that "Forgive us as we have forgiven" isn't correct theology! I don't know about you, but I want to be forgiven FAR MORE PERFECTLY than I have forgiven others!
If you can't understand why it is important for us to be able to forgive, before we can ask for forgivenss, that is your loss, imo.
