For as many as are led by the Spirit of God, these are sons of God. Romans 8:14 (NKJV)
Just as God our Father is a Spirit we His children are also spirit. We are a spirit with a soul (mind, will, emotions) living in a physical body. 1Thessalonians 5:23.
We relate and communicate with God spirit to spirit. God speaks and directs us in all the affairs of life by His Spirit who dwells in us.
As children of God we are to be led, guided, directed by the Holy Spirit and not our brain, mind, or emotions. We shouldn’t make decisions based on what we think or know in our heads or experiences. We shouldn’t live life following reason or feeling. All these voices are faulty and can lie leading to hitting miss and suffering for it.
God leads us surely, accurately, and safely by His Spirit. God always knows the right and best thing for you. He knows where you should be, what you ought to be doing, who you’re supposed to connect with at any given time. He knows your seasons when and how to get involved into something and when and how to move on to something else.
But He wants you also to know what He knows concerning your life.
The Holy Spirit knows everything Father God knows. 1 Corinthians 2:11 (NKJV) For what man knows the things of a man except the spirit of the man which is in him? Even so no one knows the things of God except the Spirit of God.
The Holy Spirit always tells us everything we need to know.
1 Corinthians 2:9-10 (NKJV) But as it is written: [” Eye has not seen, nor ear heard,] [Nor have entered into the heart of man] [The things which God has prepared for those who love Him.”] But God has revealed [them] to us through His Spirit. For the Spirit searches all things, yes, the deep things of God.
The Holy Spirit speaks to our spirit or heart because that’s where He dwells.
Romans 8:16 (NKJV) The Spirit Himself bears witness with our spirit that we are children of God,
Therefore every time you pay attention to your heart, every time you listen to and follow what’s in your heart you’re following the Spirit. Now don’t shut down or throw out your brain and emotions because God gave them to you and they have their place and function in helping you. Use your reasoning, feelings, experience, training subjected to and governed by your heart.
