Colosenses 3

Whatsoever you do, do it from the heart, as to the Lord, and not to men:

Y todo lo que hagáis, hacedlo de ánimo, como al Señor, y no á los hombres;

And what soever ye do, do it heartily, as to the Lord, and not unto men;

And whatever you do, work heartily, as for the Lord and not for men,
