The Bible defines the soul as the mind, will, and emotions. The Bible also tells us that as a baby up to and through the time He was a man Jesus had to learn and grow. He didn't know everything as a man. He had a finite and limited mind. This was His human soul. This is the soul that would die as He was nailed to the cross. The Bible is pretty clear that Jesus died for sinners. As God, Jesus didn't have to learn and grow. He was infinite in wisdom and knowledge. This is His Divine soul. This is what entered His new body when He was resurrected. The finite human soul has perished. The Divine soul lives forever.
