For this reason we also, from the day we heard of it, have not ceased to pray and make [special] request for you, [asking] that you may be filled with the full (deep and clear) knowledge of His will in all spiritual wisdom [in comprehensive insight into the ways and purposes of God] and in understanding and discernment of spiritual things--That you may walk (live and conduct yourselves) in a manner worthy of the Lord, fully pleasing to Him and desiring to please Him in all things, bearing fruit in every good work and steadily growing and increasing in and by the knowledge of God [with fuller, deeper, and clearer insight, acquaintance, and recognition].
~Colossians 1:9-10
There is only one instance that God commanded us "thus you should pray" and there is but one Prayer that He gives us to pray. That Prayer is pure supplication, because the Jews believed that prayers do change outcomes (cf Isa 38:5), and to a Jew and to Orthodox Christians, prayers make sense.
My point was based on the flawed Reformed theology of double predestination which makes any prayer a useless repetition, because prayers in a doubly predestined world cannot change the outcome God predestined.
What exactly is your point in that context?
