I was writing a letter to a new customer, suggesting her to visit our website and learn more about us, so that she could "believe us more", and that's where I got stuck in as I don't know if to choose "increase your confidence" or "strengthen your faith". I'll list the two sentences below, please help me to decide which one is better. 1. you can visit our website for more information about us, hope that could increase your confidence on our qualification and credit. 2. you can visit our website for more information about us, hope that could strengthen your faith on our qualification and credit. Regrading CONFIDENCE, I always have a sense that it's more about oneself. Is that correct? Like I always hear people say, I'm/we/re confident with sth, but rarely hear them say, i'm confident in you as for FAITH, there's a lot of expression like "I have faith in you". However, I have a feeling that FAITH is too serious in my situation, cause we barely know each other. Correct me if I'm wrong, thanks! And if you have better suggetion, please let me know!
