Clearly?
Can you show me where in the Bible it clearly says this is our “primary” purpose?
The whole thing!
It's the theme of the entire Bible!
Deuteronomy 6:5 You shall love the LORD your God with all your heart, with all your soul, and with all your strength.
Deuteronomy 7:9 “Therefore know that the LORD your God, He is God, the faithful God who keeps covenant and mercy for a thousand generations with those who love Him and keep His commandments;
Deuteronomy 10:12 “And now, Israel, what does the LORD your God require of you, but to fear the LORD your God, to walk in all His ways and to love Him, to serve the LORD your God with all your heart and with all your soul,
Psalm 45:7 You love righteousness and hate wickedness;Therefore God, Your God, has anointed You With the oil of gladness more than Your companions.
Ezekiel 16:8 “When I passed by you again and looked upon you, indeed your time was the time of love; so I spread My wing over you and covered your nakedness. Yes, I swore an oath to you and entered into a covenant with you, and you became Mine,” says the Lord GOD.
Micah 6:8 He has shown you, O man, what is good; And what does the LORD require of you But to do justly, To love mercy, And to walk humbly with your God?
Matthew 22:36 “Teacher, which is the great commandment in the law?”
37 Jesus said to him, “ ‘You shall love the LORD your God with all your heart, with all your soul, and with all your mind.’[a] 38 This is the first and great commandment.
Luke 11:42 “But woe to you Pharisees! For you tithe mint and rue and all manner of herbs, and pass by justice and the love of God. These you ought to have done, without leaving the others undone.
John 3:16 For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.
John 17:3 And this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent.
Romans 5:8 But God demonstrates His own love toward us, in that while we were still sinners, Christ died for us.
Romans 8:28 And we know that all things work together for good to those who love God, to those who are the called according to His purpose.
Romans 8:38 For I am persuaded that neither death nor life, nor angels nor principalities nor powers, nor things present nor things to come, 39 nor height nor depth, nor any other created thing, shall be able to separate us from the love of God which is in Christ Jesus our Lord.
1 Corinthians 2:9 But as it is written: “ Eye has not seen, nor ear heard, nor have entered into the heart of man, the things which God has prepared for those who love Him.”
1 Corinthians 8:3 But if anyone loves God, this one is known by Him.
1 John 4:8 He who does not love does not know God, for God is love.
I could have quoted dozens more. Indeed I could have pasted the entire Scripture in response to this question. If you do not understand that the primary purpose of our existence is to love God and to be loved by Him, you've missed the whole point.
You do know that before human history there were angels that had a relationship with God (their creator)?
Actually, you do not know this. In fact, the Bible explicitly tells us otherwise...
Exodus 20:11 For in six days the LORD made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. Therefore the LORD blessed the Sabbath day and hallowed it.
Resting in Him,
