That's the beautiful thing about the Reformed answer; it is thoroughly Biblical.

Glorify God: 

"All the nations you have made shall come and worship before you, O Lord, and shall glorify your name." - Psalm 86:9

"For from him and through him and to him are all things. To him be glory forever. Amen." - Romans 11:36

"So, whether you eat or drink, or whatever you do, do all to the glory of God." - 1 Corinthians 10:31

"Worthy are you, our Lord and God, to receive glory and honor and power, for you created all things, and by your will they existed and were created." - Revelation 4:11

Enjoy him forever:

"You make known to me the path of life; in your presence there is fullness of joy; at your right hand are pleasures forevermore." - Psalm 16:11

"Rejoice in the Lord always; again I will say, rejoice." - Philippians 4:4

"And I heard a loud voice from the throne saying, 'Behold, the dwelling place of God is with man. He will dwell with them, and they will be his people, and God himself will be with them as their God. 4 He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning, nor crying, nor pain anymore, for the former things have passed away.'” - Revelation 21:3 & 4 

 It misses the common man; needs to make it CLEAR that God himself loves us and explicitly wants us to enjoy the things he has created for us.😆 

 Yes, but only as an extension of enjoying him. To the extent that we enjoy his creation without reference to the creator is the same extent that we engage in idolatry by, "worshiping and serving the creature rather than the creator" (Romans 1:25). 

 Also note that it is man's CHIEF end or purpose, not his ONLY end or purpose. Enjoying what God has created is not our chief purpose, but is penultimate to glorifying and enjoying God himself, and flows from it by necessary consequence.
