When Jesus appeared in the sea of time, He could give the Apostles authority because He possessed all authority in heaven and earth. Being very God and very man, He had all authority. He had authority in heaven and earth at the same time. He could have called 10,000 angels to come and deliver Him from soldiers leading Him to Pontius Pilate. He had authority to do so. He also exercised His authority on earth by commanding the winds to obey His voice. The sea then became calm. What a beautiful lesson! All He did was speak to the wind and storm and they obeyed him. He had control over all the natural laws of life. Not only did Jesus have authority over the laws of nature, He likewise could delegate His authority.
God permitted Satan to use laws of nature to bring a curse upon Job and his family. Jesus gave the Apostles power and authority over nature during His earthly ministry. The Scripture reveals that God allows Satan to manifest himself through earthly elements that are under the curse of the fall; only to the extent that we allow him to operate, whether through ignorance or deception.
Regardless of what tragedy befalls us, whether by a direct attack of Satan as in Job's case or as a result of the fall, in all these things we are more than conquerors through Him that loves us:
Rom 8:37...in all these things we are more than conquerors through him that loved us.
The material things of earth are not demonic in themselves but demonic forces can use them. If the Devil can get your mind focused on earthly things, they will drive you mad. A diamond ring or a Rolls Royce can be just as demonic as a Ouija board or a crystal ball. The Devil and the demons can use these things if they can get your attention. A crystal ball is only demonic when you believe that demons can work through it. A Ouija board is only demonic when you believe it has amazing power within itself. When you believe the superstitious idea that the sun, the moon, and the stars govern your life, astrology becomes demonic. Satan and demons use everything on this material earth against humanity. Not because they have authority in their own right, but through deception.
Jesus Christ has authority over everything on earth. Jesus commanded the demons to leave and they left. Please note that all He had to do was speak to them and they went. In Matthew 8:32, Jesus simply told the devils that possessed two demoniacs coming out of the tombs, "Go" and they went. Why? Jesus possesses "all" authority!
Matt 8:29-32...And, behold, they cried out, saying, What have we to do with thee, Jesus, thou Son of God? art thou come hither to torment us before the time? And there was a good way off from them an herd of many swine feeding. So the devils besought him, saying, If thou cast us out, suffer us to go away into the herd of swine. And he said unto them, Go. And when they were come out, they went into the herd of swine: and, behold, the whole herd of swine ran violently down a steep place into the sea, and perished in the waters.That was all He needed to say.
Jesus was God! Jesus is God now! Jesus has authority over every affliction and disease. Here's an example of Jesus' authority when He told blind Bartimeaus:
Mark 10:52...and Jesus said unto him, Go thy way; thy faith hath made thee whole. And immediately he received his sight, and followed Jesus in the way.
Here's another example of Jesus' authority as He told the woman with an issue of blood who touched the hem of His garment:
Matt 9:22...and when he saw her, he said, Daughter, be of good comfort; thy faith hath made thee whole. And the woman was made whole from that hour.
Jesus possesses all authority! This is all that was necessary for Jesus who is and was very God.
In another account we find:
John 4:46-53...And there was a certain nobleman, whose son was sick at Capernaum. When he heard that Jesus was come out of Judaea into Galilee, he went unto him, and besought him that he would come down, and heal his son: for he was at the point of death. Then said Jesus unto him, Except ye see signs and wonders, ye will not believe. The nobleman saith unto him, Sir, come down ere my child die. Jesus saith unto him, Go thy way; thy son liveth. And the man believed the word that Jesus had spoken unto him, and he went his way. And as he was now going down, his servants met him, and told him, saying, Thy son liveth. Then inquired he of them the hour when he began to amend. And they said unto him, Yesterday at the seventh hour the fever left him. So the father knew that it was at the same hour, in the which Jesus said unto him, Thy son liveth: and himself believed, and his whole house.
That son began to amend the very moment that Christ spoke because Christ has authority over disease. Jesus said to the Pharisee:
Matt 9:6-7...But that ye may know that the Son of man hath power on earth to forgive sins, (then saith he to the sick of the palsy,) Arise, take up thy bed, and go unto thine house. And he arose, and departed to his house.
This is the undeniable record of God's Word. Jesus possesses "all" authority.
