You will find, particularly in the psalms, that what God is telling David is a recording of what God the Father and God the Son had already dialogued about in eternity past! In the Psalms you will find:
The Father and the Son dialoguing, conversing.
God and David dialoguing, conversing.
God and you dialoguing, conversing.
Yes, God wants to talk with you. Even while you are reading His Word He wants to talk with you. Read His words prayerfully, communing with Him, dialoguing with Him, conversing with Him.
What He tells you as a promise, you can tell Him as a prayer, even using His own words, verbatim!
It is a rare privilege that God offers to whosoever will, to enter into the very fellowship of the Godhead, inside the Triune God Himself! God longs to be one with you also. He had you in mind when He prayed what you read in John 17, longing to be one with you, as He is One with His Heavenly Father.
One important warning, however: You will never become God. Only God is God. To want to be God is a satanic ambition and because of that sin Lucifer fell and became Satan.
Jesus will become one with His Bride, the Church. He is the Head; we are His Body, the Church, with all the born-again believers as the living members.
Not only can we fellowship with God Himself, vertically, but we can also fellowship with Him in his believers, horizontally.
I desire nothing from you, my dear reader, except that you would fellowship Christ with me, flow the Christ within you to me.
Likewise, I have nothing to give you except Christ, to flow Christ from me to you.
Thus, when we believers get together and fellowship, the rivers of living waters, the flowing of the Holy Spirit pent up within us, are released and flow from one to another. That is the fellowship 1 John 1:1-4 is talking about!
Let us read verses 3 and 4: “That which we have seen and heard declare we unto you, that you also may have fellowship with us: and truly our fellowship is with the Father, and with His Son Jesus Christ. And these things write we unto you, that your joy may be full.”
Please pray with me: Heavenly Father, thank You for the fellowship You have with us. Thank you that we can share it with others. Thank You that when I commune with You, I am likewise accessing Your Son, my Lord Jesus Christ. Thank You that You inspired the apostle John to write these things down so that my joy may be full.
