Your whispers and thoughts are known to God by the Holy Spirit within you.
Today, most people forget about the Holy Spirit. He is the one that lives within you. He has the same attributes as the Father and Son. You carry the Holy Spirit wherever you go. He is with you and hears every word you speak. The Holy Spirit can grieve over the things you say and do (Eph.4:30). And when the Holy Spirit asks you to do something and you do not do it, that is disobedience and rebellion.
The Holy Spirit is the one that takes our prayer requests to Jesus, who sits at the right hand of God, who then discusses them with the Father. Romans 8:26-27 says, “And in the same way the Spirit also helps our weakness, for we do not know how to pray as we should, But the Spirit Himself intercedes for us with groaning too deep for words, and He who searches the heart knows what the mind of the Spirit is because He intercedes for the saints according to the will of God.”:
