Please read Genesis, chapters 1-26, from your Bible. Have you met someone who did not have a clue why they were here or what was their purpose of living? Take them back to Genesis to read that our sovereign God All Mighty (the Trinity), created all things and He pronounced that it was all GOOD. But it was after the creation had taken “form with a purpose”.
God the Father, Jesus, the Son of God, and the Holy Spirit all existed before creation and has always been, will always be. His realm or scope of what was created, far exist the entire physical universe and whole living cycle, of any living thing, is so complicated beyond the human mind's understanding. To this day scientist are puzzled as how it all happened and just recently discovered more galaxies of stars. Our God is such an awesome God, He has all those stars named. He reigns or rules by His will and by His power of a mere spoken word, He called creation into being. He created all that you see and more that you don't see with your naked eye. All these things are so complex and encompasses such wonder, that we still stand in awe of even how an acorn produces a huge oak tree! His authority to rule is His preexistence and holiness to make all things good, gives Him, alone, ownership. His desire to make all thing good, also reveals His holy nature and His moral right to be King.
His written Word tell us that ALL good and perfect gifts come from Him and all the earth is His kingdom, thus He rules in power and authority. But the Holy Spirit needed to hover over the earth, which was without “form” and in darkness before it took “form”. We as God's created beings, need the Holy Spirit to hover over us to have a “form or purpose” in doing just what God had in mind. In Jeremiah 29:11, He says, I know the thought I think toward you, thoughts of peace and not evil, to give you a future and a HOPE. Ask the Holy Spirit to hover over you and you will have purpose, I guaranteed it! Because God created you for a purpose and He will not lie!
