Just as we all are different, so is the method we use to speak to God. The bible is full of examples of the people during those times and various ways they prayed.
One thing’s sure; we don’t need to be on our knees, even though the act of submission in a crouched position represents a desire to get to God quickly. It's not necessary. Nor, do we need to close our eyes. It isn’t a requirement to speak the petition aloud. The interconnection we use to reach God is a personal act; that's best done from the heart.
A few scriptures in the bible that speak of appealing to the Lord and outline prayer on the knees, (1 Kings 8:54) verses also, relevance bowing the head. (Exodus 4:31)
Matthew 26:39, talks about standing. (1 Kings 8:22) People even beseeched the Lord with their faces hid. (2 Chronicles 20:18)
These are only some of the accounts spoken about in the bible. It is simple, prayer with eyes opened or closed, in silence, or voiced into a room, doesn’t matter to God. The important act of praying is enough to get God’s attention.
If there ever is a time we are unsure what to pray about, remember what Jesus said in Matthew 6:7-9(KJV).
7. "But when ye pray, use not vain repetitions, as the heathen do: for they think that they shall be heard for their much speaking."
8. "Be not ye therefore like unto them: for your Father knoweth what things ye have need of, before ye ask him."
9. "After this manner therefore pray ye: Our Father which art in heaven, Hallowed be thy name."
The Lord's Prayer Words
Our Father, which art in heaven,
Hallowed be thy Name.
Thy Kingdom come,
Thy will be done in earth,
As it is in heaven,
Give us this day our daily bread.
And forgive us our trespasses,
As we forgive them that trespass against us.
And lead us not into temptation,
But deliver us from evil.
For thine is the kingdom,
The power, and the glory,
Forever and ever Amen.
