So, let me get this straight. In today’s post-modern Christianity, I can be a Christian tattoo artist, but not hold a political office or even worse, be a political lobbyist?
Lobbying (also lobby) is the act of attempting to influence decisions made by officials in the government, most often legislators or members of regulatory agencies.
Oh! It’s because Christians shouldn’t be in politics because we are citizens of God’s Kingdom. Let their kingdom come along with it’s consequences.
Or perhaps it’s because you know I’ll end up compromising my faith and maybe even yours in the execution of my duites.
Or maybe it’s because I’ll represent tax-exempt non-profits (churches) and they’re not supposed to be involved in politics.
A Christian Woman Lobbyist said, “I believe my work is furthering the work of Christ in the community because I’m helping to bring about structural change that influences real peoples’ lives and helps them live the life that God intended for them, to help set up a more beloved community.” 
Doesn’t seem too bad? Does it? The quote above comes from a woman who works as a health care lobbyist. Darrin Mitchell said, “Truthfully, most American citizens, Christians and non-Christians alike, do not follow up their vote by contacting their states elected officials in the U.S. Congress,” Lobbying is not only to influence a policy or law in its development, but to call in to account those who have been chosen by vote to represent said legislature.
So, tell mw why I can’t or shouldn’t be a politician of a lobbyist?
Aren’t I suppose to be salt and light in every arena of life?
Aren’t Christians suppose to learn to do good; seek justice, correct oppression; bring justice to the fatherless, plead the widow’s cause? Isaiah 1:17 Sounds like lobbying to me.
