A conversation that reminded me of my faith

I've always been a Muslim, alhamdulillah, and my belief in Allah is unwavering. I pray consistently and am also fasting this period, alhamdulillah. Recently at work, I met someone who was deeply devoted to Christianity. He inquired about my beliefs, and I explained that I follow Islam, but our time was limited. He shared with me that he became baptized and felt it was his mission to encourage others to explore Christianity, inviting me to his place of worship. I told him that while I was raised in a Muslim household, as I grew older, I made a conscious choice to learn about my faith, and it truly resonated with me. I did mention to him that I'd consider looking into the scriptures he referenced, though honestly, I wasn't planning to. He appreciated that I seemed open-minded, so I extended an invitation for him to visit the local masjid, where he'd be warmly welcomed without judgment. He affirmed his commitment to Christianity. During our talk, I also shared a beneficial website that discusses the miraculous aspects of the Quran. Reflecting on it, I feel a bit uneasy about not being completely truthful. It made me question if, for a moment, I doubted my deen, even though my faith in Allah is strong and I continue to pray and fast. I just wanted to be honest about that feeling.
