What's the purpose of this life? Is it just to enjoy ourselves in these times?

Make sure that nobody pays back wrong for wrong, but always try to be kind to each other and to everyone else. Be joyful always; pray continually; give thanks in all circumstances, for this is God's will for you in Christ Jesus. 1 Thessalonians 5:15-18

For all that is in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world. 1 John 2:16
