I have examined every sect of Islam, Sunni, Shia, Ibadi, Quranists, and I still don't know which one is the correct way. How can I make my faith stronger in the correct and true Islam?
It is good to continue to pray for guidance and to find the truth (as we all must do regularly!), since Allah answers those who sincerely pray for guidance. It is also good to follow whatever you know is true. Lastly, it is good to reflect on the Qur'an (I am sure you do that, but doing that more be helpful, as our understanding of the Qur'an often changes as we go throughout life).
