Dyothelitism is a belief that Jesus Christ has two natures, one divine and one human. This means Jesus was both fully God and fully human at the same time. He was not just an ordinary man that God made special or just a spirit from Heaven that looked like a man. He was both fully God and fully human so he could understand us and help us. This helps us understand why Jesus was so wise and why he was able to heal people and do miraculous things. Dyothelitism is part of a bigger belief called Christianity which is a religion all about Jesus and his teachings.
