Will I be Heard Because of my Many Words?

Simple answer is not neccessary but lets read further into this passage of the Lords prayer to see the answer to the proposed question.

Matthew 6:7-8
"And when you are praying, do not use meaningless repetition, as the Gentiles do, for they suppose that they will be heard for their many words. "Therefore do not be like them; for your Father knows what you need, before you ask Him.

Pagans and Jews alike thought they could be heard because of their many words. To do this they used what the prayer describes as "meaningless repetition". We need to hold on to this thought that it is not requirement for us to pray long lengthy prayers in order for us to be heard.

The encouraging thing is that before you come to him surrendering yourself in prayer, the Father in Heaven knows what you need. So it is not even the case we need to pray long in order to inform him of the full story. It is good to know that the Father is waiting for us to surrender ourselves in prayer to him.

In prayer, we do not look for praise from others nor are we trying to manipulate God so that we get our own way. This is why we pray Father, let your will be done in the Lord's prayer!
