Q/A#1
Q: What is our primary purpose in life?
A: Our primary purpose in life is to love God and people, in response to His love for us, for the glory of God.

And he said to him, “You shall love the Lord your God with all your heart and with all your soul and with all your mind.  This is the great and first commandment.  And a second is like it: You shall love your neighbor as yourself.  On these two commandments depend all the Law and the Prophets.”
– Matthew 22:37-40 (ESV)

And walk in love, as Christ loved us and gave himself up for us,
a fragrant offering and sacrifice to God.
– Ephesians 5:2 (ESV)

Not to us, O Lord, not to us, but to your name give glory,
for the sake of your steadfast love and your faithfulness!
– Psalm 115:1 (ESV)
