Whatever you do, do it heartily, as to the Lord and not to men.
Colossians 3:23
Paul defined the Lord's work as
"Whatever you do." Because we are servants of God, everything we do is considered part of that service. God makes no distinction between what is spiritual and what is secular... All of us who know the Lord - homemaker, banker, mechanics, assembly line work, construction work - are involved in God's work... It takes just a much dependency on the Holy Spirit to do any of these jobs well as it does to preach a sermon or sing in a choir. In some cases, it takes much more.
