This is a POWERFUL DREAM.
I believe the dream is showing that you were in the right place at the right time to receive a revelation from God. Light illuminates and it brings clarity in areas that there is darkness.
Is there something you aren’t seeing clearly at your church or in your life?
Or are you called to help people see correctly in the church? In the world? And in other atmospheres?
Are you someone that already has wisdom and sees things at a deeper level than others?
It’s interesting you weren’t afraid. I believe this is because you already carry truth, justice, order, and wisdom. However there seems to be a current or future message God has for you the is a little more powerful than you are use to. And it’s because he’s refining your gifting and taking you to another level 🙂
