Living a life of excellence means living at your best, giving your all. When the day comes to stand before God and answer for all you have done, He will not just ask what you have done, but how you have done it. He will be specifically looking for excellence. Did you give God only the leftovers or did you give Him the best you could, even in the smallest tasks in life? You see, God wants you to rise to a higher standard, He wants excellence in all you do!
God's excellence is to serve as your model -Sing unto the ; for he hath done excellent things: (Isaiah 12:5). God wants excellence from us because we are a child, made in His image!
Paul wrote in Philippians about not yet attaining, nor being perfect but instead pressing toward the mark for a prize of the high calling.
And whatsoever ye do, do it heartily, as to the Lord and not unto men. -Colossians 3:23
