Our major purpose which God created us is for us to honour him and worship him till the rest of our life here on earth. Human beings were created in God's image to reflect His goodness, love one another, and care for His creation. Our lives find true meaning when we seek a relationship with God and faithfully obey His commandments.
Our existence is also meant to prepare us for the eternal life that God has promised to those who remain faithful. Rather than living only for temporary pleasures or earthly success, the Bible encourages us to pursue righteousness, serve others with love, and glorify God in everything we do.
"Seek first the kingdom of God and His righteousness, and all these things shall be added to you." (Matthew 6:33)
