Jesus was the image of His Father. Now we are to become the image of Him to the world.
Our privilege in life and the reason Jesus died and rose again was to establish an eternal covenant for us with His Father. In that covenant, Father God promised to do whatever it took to make us look and act like Jesus in a dead and dying world.
What's the point of the horrible death of Jesus, the cross and all it means, and the astounding resurrection if we don't submit to our Father's refining hand on us? Our goal should not be to live so God can serve us. It's to live and die to everything we once were by the power of the Holy Spirit!
