The Jupiter sign in a person’s birth chart is one of the outer planets, so it doesn’t really represent someone’s personality. The outer planets, I believe, are expressed most strongly through their aspects to the inner planets (Sun, Moon, Mercury, Venus, Mars), as well as if they are placed in the angular houses/conjunct one of the angles. (Also, of course, the house that the outer planet's in really influences its expression). If your Jupiter doesn’t make many aspects to these five core planets, then it might be harder for you to channel its energy. If your Jupiter is in aspect to two or more, then you might be more in touch with it. Either way, we all must find ways to express our Jupiter. We do so by using it to trust in the unfolding of the Universe.
Jupiter is about personal growth and expansion; the attitudes and beliefs that assist us on our way through this big adventure called life. Embracing these beliefs will allow us to grow as people, as well as to attract good fortune and abundance into our lives. People with a strong Jupiter influence can seem to be the lucky ones, catching one good break after the next and living life with a constant smile on their face. However, we all have the potential to benefit from Jupiter’s golden touch. Jupiter also rules religion but it doesn’t necessarily make you religious or not. We should just see this as a metaphor. Our Jupiter sign describes the “God” we must pray to, in a way, asking for guidance on our journey as well as to be blessed with good things in our life.
Also, Jupiter is whole-hog. So, you can’t just express your Jupiter sign’s faith with a half-hearted sense of belief. Like many people with their religion, your Jupiter’s beliefs need to be something that no one and nothing can talk you out of. You must be totally devoted to them.
