Jesus came from heaven to die for mankind and to leave himself for mankind to walk in. Think about this, according to Jesus he left himself here for you and me to partake of. What did he leave of himself? He left his body, his blood, his name, his spirit. Through communion Jesus said of the bread, "Take, eat; this is my body which is broken for you. He said it is his body so since it's his body it is anointed. In Luke 4:18 Jesus said, "The Spirit of the Lord is upon me." And when people made contact with that anointing the scriptures say that power went out of him and healed them all. That's the anionting you take in, but you have to put faith in it. And Jesus said of the drink, "For this is my blood of the new testament, which is shed for many for the remission of sins." Jesus didn't have natural, human blood like you and me for we came from flesh. But, Jesus flesh and blood came straight from the father because he is the word made flesh. And the word of God is spirit and life and it's that life that made his body (the life of God). And according to Leviticus 17:14 the life of the flesh is in the blood. So, the life that was in Jesus is in that drink, but again you have to put your faith in that. It has to be a revelation to you.
He left his name(authority) for us to walk in. He said, "All power(authority) is given unto me in heaven and earth. Go ye therefore..." He wants you to walk in his authority and he invites you to do so as in Colossians 3:17, "And whatsoever you do in word or deed, do all in the name of the Lord Jesus, giving thanks to God the Father by him." He wants you to speak in his name because when the authority of Jesus is released the power of God backs it. In Luke 10 Jesus gave authority to 70 others than the 12 disciples and it says, And the seventy returned again with joy, saying, Lord even the devils are subject unto us through thy name(authority). He gave them authority and power followed them through that name. When you speak in his name his authority works through you like it did through the disciples. Jesus said, "If ye shall ask(demand) any thing in my name, I will do it." Let me make this note, when it says demand you are not demanding God, like with Peter and John in Acts 3 when Peter said to the crippled man, "Silver and gold have I none; but such as I have give I thee: In the name of Jesus Christ of Nazareth rise up and walk." And he took him by the right hand, and lifted him up: and immediately his feet and ankles bones received strength. Notice he didn't demand anything of God, but demanded that the man rise up. Because, when you demand something in the name of Jesus the power of God backs it for it to be carried out. Notice in Acts 3:13 Paul said that it was God that did it. We are to speak in that name and watch the power of God do the work.
He left you his spirit, the same spirit that guided and directed him is going to guide and direct you. The same spirit that worked through him is going to work through you. That same spirit is going to open the word up to you and give you revelations of the word. The same spirit then is the same spirit now. If you are to do what he did then you have to have what he had. The Spirit wants to work through you like he worked through Jesus. God wants to work some mighty things for us and through us, but the question is what are you going to do with all Jesus left for you to use.
