The Author of the universe did not simply cause you to exist by just some normal random act of chance. Rather, He created you for a divine purpose. In God's kingdom, all of the creation shall discover their respective ultimate purpose.
Jesus, while He was on earth, had told so many things that described what the kingdom of God is like. In essence, He was describing the way of life and how things work in God's kingdom. He was revealing creation's ultimate purpose in the heavenly kingdom!
Therefore, the most fruitful and meaningful thing we can achieve in life is to live life according to God's purpose for creating us.
Whatever status in life we might be in, and whatever endeavors we might be trying to accomplish, let all of these be according to God's purpose for all of us in His kingdom.
