"And be not conformed to this world, but be ye transformed by the renewing of your mind, that ye may prove what is acceptable, and perfect will of God"
Romans 12: 1-2
God being the creator of man expect man to utilize his life for His glory or pleasure. It was what apostle Paul was seeing that made him appeal to man to live that is in the conformity with God's standard.
Everyone has been given a service to render, so our life should be in accordance to what God has said and given us.
World should not be our standard but in God our maker. Our heart, mind and totality should be unto God.
