Serving the Lord & His People
*Disclaimer: Believers in Christ are called to serve the Lord and His church with all their hearts; an act of their own volition. Though I do not advocate using the term "volunteer" to describe service work in the church, servants of the Lord are instruments of God's will and not a title of nobility (1 Peter 2:16), I choose this adjective to clarify for employers that the roles I have adopted over the years and will continue to pursue are non-profit efforts without pay. These efforts do not and will not compromise my commitment as an employee to a given organization. This disclaimer is meant to eliminate any concern of moonlighting or conflict of interest.
"Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood" [Acts 20:28]. "For, brethren, ye have been called unto liberty; only use not liberty for an occasion to the flesh, but by love serve one another" [Galatians 5:13]. "And whatsoever ye do, do it heartily, as to the Lord, and not unto men" [Colossians 3:23]. See Matthew 25:40, John 13:14-15, Galatians 5:13, Ephesians 6:6-7, Colossians 3:23, and Acts 20:28.
