I have brought you glory on earth by completing the work you gave me to do (John 17:4).
The Lord has revealed to us that the number one thing we are to do is love the Lord our God with all our heart and to love our neighbor as ourselves. His desire is for us to know Him and the power of His resurrection. These mandates deal with our relationship with Him. The fruit of this relationship must then result in our glorifying Him by completing the work He has given each of us to do. It will become a by-product of this relationship, not an end in itself.
What is that work God has called you to do? Jesus never did anything the Father had not instructed him to do. He lived in such communion with the Father that He knew when to turn left and when to turn to the right. Is it possible to have such a relationship with our Heavenly Father? I think that if it weren't, He would not have given us such an example.
"Call to me and I will answer you and tell you great and unreachable things you do not know" (Jeremiah 33:3). What has he called you to do? Perhaps you are called to be the best CPA in your city or the best advertising executive or the best office worker or assembly line person in your company. Whatever work he has called you to do, he will use you as His instrument to accomplish something through you that He has uniquely prepared you to do.
When our life is complete, what a glorious day it will be if we can each say "I have completed the work you gave me to do." This will have brought great glory to Him.
