Because the Gemini sign of the zodiac is so flighty and flirty, these people specifically are into faith. They live life so quick paced that they have little time to stop and think about it all. However, since they love science they might take on science as a more faithful approach to life. In this case, they might actually use science as a backbone to their understanding and appreciation of life.
Science speaks to them and in turn, they tend to listen! The Gemini people usually use faith to explain their personal preferences about life. That could be religion, or any other spiritual practice. Most Gemini learn to have more faith in their lives as they get older and mature a little. Their hard life experiences may ultimately teach them to joys and pains with life and that faith can get you through them easier and unharmed in a way. Since they are like little children, they will learn to appreciate faith through their children. They see the world better at large and see it for all the potential that it has. Gemini is the innocent soul, so the faith they have or gained throughout their lives is rich and honest. They may view faith in a way that is clean and pure, like it should be.
