* We can speak our prayer
Matthew 6:5-6 And when thou prayest, thou shalt not be as the hypocrites are: for they love to pray standing in the synagogues and in the corners of the streets, that they may be seen of men. Verily I say unto you, They have their reward.
But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly.
* But the best prayer is secret prayer
1 Corinthians 14:15 What is it then? I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also.
* If you are going to pray alone, you can pray secretly, go to a place where nobody can see you so there would be communication between your mind and God's mind
* Satan cannot even hear your prayer because Satan is not permitted to see minds, the minds and hearts ♥ is something secret to Satan
Jeremiah 17:9-10 The heart is deceitful above all things, and desperately wicked: who can know it?
I the LORD search the heart, I try the reins, even to give every man according to his ways, and according to the fruit of his doings.
* If you pray in secret, Satan cannot know because only God sees mind, praying in secret may give you quick answer because nobody can infer it
