“That they may be one, Father, just as you are in Me and I am in you” John 17:21
Most believers compartmentalize their relationship with God. They are somewhat attentive in church, praying, or reading the Bible. Then they go about life with very little or no consciousness of God. This is where troubles arise because they are functioning from self.

God did not design you to tune in and out of Him at your own volition. He wants you to live in oneness with Him at all times.
God knows you can never match up to His standards of holiness. So He sent Jesus to die for you. This provided a way for you to be forgiven for your sins and restored to God.
But the Cross did not address the need to live in oneness with God. Just think about the disciples. They were confused and without a clue until the Holy Spirit came to them.
God sent the Holy Spirit to dwell in all believers. The Holy Spirit is the essence of Christ in the form of a spiritual being.
The Holy Spirit is how you can live in oneness with Christ. He speaks to you by placing His thoughts in your mind. You have the mind of Christ so it is just a matter of learning to be still and listen for the voice of God.
The Holy Spirit also gives you dreams and visions. And, the Holy Spirit equips you with the gifts of the Spirit. This empowers you to be a powerful witness for Christ.
The Holy Spirit is your conduit to the Living Christ. Without the Holy Spirit you will just flounder through life and never experience the transfigured Christ.
The Holy Spirit keeps you on track with God and convicts you when you stray away from Christ.
If you choose to live for self or close God out from parts of your life you will quench the power of the Holy Spirit. He will still be in you but in a lackluster form.
Today, the Holy Spirit wants to help you navigate through life. He wants to order your day and show you the priorities. He wants to teach you how to apply the values of Jesus into the real time of life.
He lives so you can live!
