The Holy One

John 1:18  No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him.

No one has seen God, the Father or the Holy Spirit. They are spirit. The Son of God has made himself visible to us. He took on the form of a man; and now He exists in heaven in a glorified body.  The Bible says that he existed with God before the foundations of the world. there are times in the old testament when a visable man is shown who is of God. One incident was when Joshua was about to war with Jericho. 

 Jos 5:13  When Joshua was near Jericho, he looked up and saw a man standing in front of him. The man had a sword in his hand. Joshua went to the man and asked, "Are you a friend to our people or are you one of our enemies?" 

Jos 5:14  The man answered, "I am not an enemy. I am the commander of the LORD'S army. I have just now come to you." Then Joshua bowed his face to the ground to show respect and said, "I am your servant. Does my master have a command for me?" 

Jos 5:15  The commander of the LORD'S army answered, "Take off your sandals. The place where you are standing is holy." So Joshua obeyed him. 

The commander of angel armies was the Lord of Lords. An appearance before his coming to die for our sins as the Lamb of God. Was this the same person who appeared to Moses in the burning bush?

Exo 3:4  And when the LORD saw that he turned aside to see, God called unto him out of the midst of the bush, and said, Moses, Moses. And he said, Here am I. 

Exo 3:5  And he said, Draw not nigh hither: put off thy shoes from off thy feet, for the place whereon thou standest is holy ground. 

The Son of God is commander of the LORD'S armies.
