What else is around the Disciples' Prayer? What led to Jesus teaching on prayer, here?

Matthew 6:5-8
Lord’s Prayer, Week 1: Intro context

Father,
As we approach the Disciples’ prayer today, help us to see this ever-so-familiar passage in fresh ways, help us to grasp the deep things in it, not just the simple, surface meaning.

5“Whenever you pray, be sincere and not like the pretenders who love the attention they receive while praying before others in the meetings and on street corners. Believe me, they’ve already received their reward. 6But whenever you pray, go into your innermost chamber and be alone with Father God, praying to him in secret. And your Father, who sees all you do, will reward you openly. 7When you pray, there is no need to repeat empty phrases, praying like the Gentiles do, for they expect God to hear them because of their many words. 8There is no need to imitate them, since your Father already knows what you need before you ask him.

When the disciples asked Jesus how they should pray, this is how he started his teaching. Don’t try to focus attention on yourself as you pray (like the pharisees do). Instead, go as far from others as you can. Hide that you are praying, so that God will do the opposite and put you on blast for praying privately. Prayer is not meditation, muttering and murmuring repetitive phrases (like those who do not know God) will not cause God to respond more favorably to you. Be simple and to the point, because our Father knows what we need and desire before we ask. Be at peace. Speak your mind and your heart to the Lord. Even though He knows already, He likes to hear from each of us. Doesn’t that make you thankful? Even though He knows about all our needs and desires, He wants us to tell Him about them, if only to build relationship. Doesn’t that blow your mind? The God of the universe wants to hear from YOU.
