Once again, what an amazing story, and what an amazing Christian friend you have. Isn’t that incredible how God can work through people who completely give their lives over to Him. It’s a miracle to behold, when Christ can save people through His Church, like that, in the darkest places imaginable. Sometimes God allows broken people to go down to the depths of hell, because it is there that they might finally reach up to Him, and ask Him for help because it is the only thing left to do.
If there is a person so loving and good that will go where God tells them to go, like your beautiful friend, Christ can work through that person and can even speak through that person to share the Gospel to save there souls, which is the ultimate help He can give them. If you pray, and ask God to talk through you, to an unbeliever, He will, “ask and you shall receive” God says. Your Christian friend, united as one with Jesus, together they become the light in the darkness, the lamp on the stand, the refuge they have prayed for❣️

If then your whole body is full of light, having no part dark, the whole body will be full of light, as when the bright shining of a lamp gives you light.”
Luke 11:36

I hope you can read the words on the picture that I drew, if not it says -

For you are my lamp, O lord; The Lord shall enlighten my darkness
2 Sa 22:29
