How Not To Pray (6:7-9a).
Having gone quietly and secretly into a private room the next question was as to what kind of praying to avoid. The point being made here is that the prayers of most men are useless, and accomplish nothing, simply because when they pray it is not a question of genuinely speaking with God. To them God is just a convenience store. Their aim is simply to get what they want. And they rather think that by repeating themselves and going on and on in prayer they will somehow persuade God to give them what they want. So they ‘babble' on. They somehow feel that they will earn God's reply by the length of time that they continue in prayer, and by how often they repeat their request. Their idea is that if they keep it up long enough they will surely eventually have earned a satisfactory reply. They think by such methods to persuade Him to do what they ask. Jesus stresses that His disciples must not think like that at all. For they must remember that they are speaking to a Father Who knows what their needs are before they ask Him, and will cater for them as necessary (Matthew 6:26; Matthew 6:30).
He is not discouraging long prayers. Only long prayers for the wrong things and with the wrong motive. Long prayers made with the hope of their length somehow persuading God to do something selfish are discouraged, but long prayers of someone whose aim is simply to have loving fellowship with God are a different matter. Once He has made the point He will then go on to point out what they should be praying for all the time.
Analysis of Matthew 6:7-9 a.
a A “And in praying do not use vain repetitions, as the Gentiles do,
b B For they think that they will be heard for their much speaking.
c C Do not therefore be like them,
b D For your Father knows what things you have need of, before you ask him.
a E After this manner therefore pray you.”
Note that in ‘a' they are to avoid vain repetitions, and in the parallel they are to pray as Jesus shows them to pray. In ‘b' the non-disciples think that they will be heard because of their constant repetition, and in the parallel the disciples are reminded that such is unnecessary because their Father already knows their needs. In ‘c' and importantly they are not to be like the Gentiles. Thus while they are to avoid being like the more ostentatious Scribes and Pharisees, it is equally necessary that they do not pray like the Gentiles. Their way of praying must rather be that of a true disciple.
