“All things that the Father has are Mine. Therefore I said that He will take of Mine and declare it to you.” John 16:15

You can’t really delineate between Jesus and God! They were one from the beginning of time. Jesus is in possession of all the qualities of God.
Jesus is explaining in this verse in the Book of John that God will take what belongs to Jesus and give it to you. This is accomplished through the Holy Spirit who lives in all believers.
As a believer, you have the life of Jesus residing in you and He wants to share His life with you. The Holy Spirit is a person and God desires for you to one with Him. You can do this through prayer and developing an inter consciousness with the Spirit.
You have to abandon yourself completely to God to receive the fullness of the Spirit. If you close God out from compartments of your life you will quench or diminish the power of His Spirit.
Companionship is a warm and close relationship with another person. You can have this intimate rapport with the living God. He wants to be your best friend. He wants to be the most vital part of your life. He wants to speak to you and guide your footsteps.
You have the mind of Christ and He desires to fill you with His thoughts. You accept His voice by faith with an open mind to receive Him.
Your companionship with God is built on faith in His name. You learn to trust Him for your every need. You walk with God by faith trusting in His promises.
You dwell with God through prayer, His Word, and a sensitivity to His Spirit.
Make God your best friend! He will never disappoint you!
