Faith and confidence

As a general rule, it is impossible to explain two commandments in one word, especially if you consider them difficult. Therefore, you must specify exactly what is difficult and what you are asking for. Leave the number of words and lines to me. I’ll just say in advance that neither of these two is a mitzvah. Confidence certainly isn’t, and faith is indeed mentioned in the Rambam (Esa 1), but it’s a very puzzling matter and doesn’t seem right to me.
