God loves us so much that he can die for us himself. But the point is that we can't understand him, we can't understand him. It is normal for us to have doubts when facing many problems, but we can't know God by doubts, so there will be many complicated problems. Therefore, we should know God and Christ in Christ, and have answers when facing problems. I suggest reading Christology.
As for many literary, artistic and musical works in Christian history, are they all in line with God's will? The key is the relationship between the creator and God at that time. Every artistic creation has an idea, which directly shows the image of Jesus and easily leads to idolized understanding. Generally, it is expressed by metaphors and symbols, such as the relationship between shepherd and sheep, the relationship between father and son, and the way of scene reproduction.
