A Seeker's Heart: Embracing the Truth about Prophet Muhammad (PBUH)

As-salamu alaykum, dear brothers and sisters. I am on the beautiful and sincere path of considering reverting to Islam, but I find myself needing some personal insight and perspective from the community. I was raised in a Christian environment, and from that upbringing, I was taught certain things about our beloved Prophet Muhammad, peace and blessings be upon him. These teachings have created a significant hurdle in my heart and mind-like the idea that he was not a true prophet. It has caused a lot of internal hesitation for me. I truly believe in the truth of the Quran and in the Oneness of Allah, but this one block from my past is holding me back from fully accepting the prophethood of Muhammad (PBUH). I would be so grateful for any gentle guidance, advice, or personal stories you could share to help me overcome this final obstacle. May Allah guide us all to what is correct.
