@Person... I know you are there, and I love you. Am I saying a prayer to you when I say that? (Nope.🙂) You are "invisible" to me as far as I can't see you with my physical eyes right now. But I know you are there. If I tell you I love you, am I saying a prayer to you? I am not saying a prayer to you. I know you can "hear" me via what I am typing, and I am not ashamed to talk to you, just like I am not ashamed to talk to Jesus. I know you can hear me, and I know he can hear me too. He is not "answering back" with words that we can hear at this time, but that doesn't mean we can't talk to him. Talking to someone is not prayer. I can talk to you without worshipping you. I can talk to Jesus without worshipping him. Just because we can't hear Jesus when he speaks or just because we can't see him right now doesn't mean he isn't listening or that it is wrong to talk to him.
"Listen, you who are deaf;
Look and see, you who are blind.
Who is blind except my servant,
So deaf as the messenger I send?
Who is so blind as the one rewarded,
So blind as the servant of Jehovah?" (Isaiah 42:8,9)
We are "deaf" in so many ways, but that doesn't mean Jesus and Jehovah are deaf. We are "blind" in so many ways, but that doesn't mean Jehovah and Jesus can't see.
"He does great and unsearchable things,
Wonderful things that cannot be counted.
He passes by me, and I cannot see him;
He moves past me, but I do not discern him." (Job 9:10,11)
They can hear when we speak. They know whether we are praying or just talking.
"The One who made the ear, can he not hear?
The One who formed the eye, can he not see?" (Psalm 94:9)
