Christian art is generally created as an expression of what the church may believe. Since there are several different types of Christianity, or branches under the large name, the church the artist goes to, or whatever religious ideas the artist has will be portrayed in his artwork. Christian art is made to support their ideas and religion, as well as give people a sort of image to look up to. After all, nobody truly knows how God looks.
Sometimes people don't want to continue in something they aren't good at because they either don't like to work for it or they don't like having something they can't do. They want to excel in every aspect of their life. But some people, like me, just realize that they are not good and don't necessarily see it taking them anywhere, so they don't try. You understand?
