I want to give you a quote from my dad that I believe is related to some degree with your question and it goes like this:
"Deep within each and every human spirit lies the knowledge of something out there that is far greater than ourselves."
I believe this quote is every true. Inside each of us is a spirit that seeks a relationship with our creater. The part of us that seeks for "our purpose" in life come from the spirit part of us. God created us to worship Him. This was our purpose when we were created. Our spirit was given to us at creation. Without it we would not have existed. Because our spirit is needed in order for to worship. Our spirit at the time of creation was just as pure as Jesus Christ's spirit was when He walked this earth throughout His life time. But the fall of man removed that purity of the spirit within man. Our spirit, although it was still there, was corrupted.
Because of Christ Jesus and what He did for us we now have the means to, once again, worship God in Spirit and in Christ TRUTH is revealed.
Jesus Christ said the following in John 18: 37 (NKJV) which states:" Pilate therefore said to Him, Are You a king then?" Jesus answered " You say rightly that I am a King. For this reason I was born, and for this cause I have come into this world, that I bear WITNESS to the TRUTH. Everyone who is OF the TRUTH hears MY voice."
Notice He said "Everyone who is OF the truth hears MY voice." Truth is through our Lord Jesus Christ. He was born to be a King and to bear witness of the TRUTH of the Kingdom of God.
This is the exact position we once had in the garden of Eden. A part of God's Kingdom on earth.
It was also said in Matthew 13:34 which States: that it might be fulfilled which was spoken by the prophet, saying: I will open my mouth in parables; I will utter things kept seceret from the foundation of the world.
Those things Jesus Christ uttered in parables was about or directly related to the Kingdom of God.
The Garden of Eden had the Tree of Life and so will the New Jerusalem on the new Earth.
When we worship in spirit and in truth. We worship God as King we acknowledge He has an everlasting Kingdom and the truth was revealed through our Lord Jesus Christ. In worship we seek first the Kingdom of God and His righteousness as we study God's word.
We can avoid darkness and false witness by staying focused on God (our King), our Lord Jesus Christ, and listen to the Holy Spirit as He reveals the wonders of His Kingdom.
