Heartily

"And whatsoever ye do, do it heartily, as to the Lord, and not unto men;

Knowing that of the Lord ye shall receive the reward of the inheritance: for ye serve the Lord Christ."

(Colossians 3:23-24, KJV)

Do whatever you do heartily, don't grumble and complain or do it for show but go forward with sincerity and do it with all your might!

Do it unto the Lord who knows your heart. Don't do it to look good or for others but do it with honesty and out of love for Christ. If you are doing it for the right reasons then you will receive the reward of inheritance for ye serve Christ and not men or men's approval. If you do it for praise, you are not doing it for God. If you do it to seem righteous, you are not doing it for God. If you do it to make your family happy, you are not doing it for God. 

Do it for the Lord!
