These two letters shared are my examples from my moments in life in the retail and public sector jobs I have held and experienced the bullying of Christians in the workplace by those who practice in the dark arts.

For we are to God the fragrance of Christ among those who are being saved and among those who are perishing.
To the one we are the aroma of death leading to death, and to the other the aroma of life leading to life. And who is  sufficient for these things?
2 Corinthians 2:15-16
New King James Version

We have not received the spirit of the world, but the Spirit who is from God, that we may understand what God has freely given us. And this is what we speak, not in words taught us by human wisdom, but in words taught by the Spirit, expressing spiritual truths in spiritual words.
1 Corinthians 2 : 12 - 13
New King James Version
