there are different ways you could go about it.
I think trying to understand the existence of a Divine Being without any religous connection is a good first step. that way you won't be distracted by ritual, or other humans or mythology. a very simple way to start off is in your mind sincerely pray for guidance to find the truth. give yourself some time and space to find answers and be open.
you can also try to experience religion/spirituality. go to church services, I reccommend something like a methodist church which is very pared back. you can also try to experience other religions. maybe visit the golden temple in amritsar (or a local gurdwara), visit sufi shrines (plenty in Turkey, there is only one in uk) and mosques, synagogues, Buddhist monasteries etc.
listening to spiritual music from different religions and reading religous texts are also good options.
disclaimer I am not a Christian (I am a religous sufi muslim) but know many pious Christians who gain perspective, peace and joy from their faith. for me, faith brings me serenity, a sense of deep connection to both creation and the Creator, contentment and purpose. it is a long journey and I am still learning every day. I started off in the ways I described above.
