Predictive text failures

My apple phone has anticipatory texting that I appreciate and use very much because I am not a fast typer/texter. One of the most common words I use is God. I don't think my phone has once anticipated that word or the letter d even when I type the first two letters G and o., why not? The reason that I wonder why not is because it works so well for me on just about every other imaginable word, even supplying entire words that I don’t even start typing, even whole phrases with numerous words. I don’t like to think so but it makes me wonder about a bias against religious speech.
