God also created us with a different personality. Jesus was perfect man and perfect God, in God's eyes He was always seen as holy. Except for on the cross when He bore all of our sins upon Himself, but it was also something which lifted Him up in glory afterwards!
You need to be born again to truly understand the ways of God. Without the leading of the Holy Spirit, you cannot understand the meaning of living a life as a Christian.
An example is during the transfiguration of Jesus Christ. Jesus met on a high mountain Elijah and Moses, which were recognized by the disciples. They had been long dead, yet they were still recognizable.
Matthew 17:1-6
After six days Jesus took with Him Peter, James and John the brother of James, and led them up a high mountain by themselves. There He was transfigured before them. His face shone like the sun, and his clothes became as white as the light. Just then there appeared before them Moses and Elijah, talking with Jesus.
Peter said to Jesus, “Lord, it is good for us to be here. If you wish, I will put up three shelters—one for you, one for Moses and one for Elijah.”
While He was still speaking, a bright cloud covered them, and a voice from the cloud said, “This is my Son, whom I love; with Him I am well pleased. Listen to Him!
When the disciples heard this, they fell facedown to the ground, terrified. But Jesus came and touched them. “Get up,”He said. “Don’t be afraid." When they looked up, they saw no one except Jesus.
God is creative. He didn't make all the angels the same way either. Look also at His Creation. All of the animals, many different types! Look at nature, there are also many different forms and sceneries! It should be clear that there is a great Creator behind this all!
