Of course your friend feels "threatened". Men hate the light because their deeds are evil. What you presented to him was the light of Christ, with no "strings of darkness" attached.
That's the same as when the voice of the Lord spoke to Adam in the garden. As soon as Adam heard the voice, he realized his condition, and ran from God. What you're speaking now is much closer to His voice than he's ever heard before and "Adam" in him is going to want to run........at first.
But as you manifest unconditional love in spite of his trying to run, sooner or later he's going to be drawn to that love because He said if I be lifted up, I will draw all men unto Me. I've seen it work before and it's awesome to behold the power of God in that way.
I'll give you an example. In a hotel job I used to have when I was much younger, I worked with a young girl. She had been on maternity leave when I was hired, and they gave me her position on days, so that when she came back she had to go on nights for awhile until there was another opening. A couple of months into it, there was another opening and that put her working with me. She wouldn't speak to me unless it was absolutely necessary and if I tried to speak to her she would roll her eyes and give me a dirty look. She did this for 9 months. She ridiculed me to the other staff, she did everything she could to get back at me for something I had no control over in the first place.
Finally, one day she came in with a huge black eye, badly hidden by make-up. Her boyfriend whom she had 3 kids with, had beat her black and blue, and I found out later, this wasn't the first time. She broke that day at work, and I was the one He had placed there to pick up the pieces.
She let me pray for her, and she received the HG (she had gone to Church of Christ as a young girl), she began to get strong in the Lord after that, day by day, reading her Bible........oh, and she had a love for me now that He had deposited in her. We were only about 7 years apart in age, but she called me "mama" (because she recognized I had been used to birth her into the Kingdom), and on Mother's day that year, I was reduced to tears as she brought me in a Mother's day card with an African violet.
Then it was her turn. She had to stand and be different with her boyfriend. The Lord didn't make her move out right away. Instead, she had to show HIM unconditional love. It started to make a crack in his armor right thru the alcohol abuse and verbal abuse (he never hit her again after that). Finally, the Lord did have her move out, but he was already "hooked" by the love, and he was a broken man when she left him. She led him to the Lord and he received the HG, and got free of the tormenting spirits. They got married and the Lord was the Lord of their home.
We can't look at their "faces". We can't look at their reactions, because that is subject to change. We just have to keep our eyes on His face/nature and reflect it to others, and leave it to Him to do the rest in His season. It really works. Blessings to you and may He strengthen you in all things for His glory.......
