The secular world recognizes the need for meaningful relationships in life. That includes family and friends. Life is relationships and the most meaningful one is ultimately found with God. It is really knowing God through a personal relationship. Enjoy God now and forever. Rejoice in the Lord always, and again I say, rejoice (Philippians 4:4).
God made you for himself. He made you for the praise of his glory. Your heart is never satisfied until you discover the joy of a relationship with the One who made you and loves you. He made you for a purpose, and that purpose is to rejoice in the Lord always.
Your relationship with God is through Christ. Your union and communion with God is through the Holy Spirit. The fruit of the Spirit is love, joy, peace (Galatians 3:22). That's your joy in life through Jesus Christ. Then, and only then, you can truly say, I will rejoice in the Lord always.
God's purpose in your life is an eternal relationship through Jesus Christ our Lord. Read the Bible to know how to enjoy your relationship with God. That's God's purpose and good will in your life. It's a relationship of rejoicing in the Lord always.
