>In Thessalonians paul says that satan prevented him from visiting the church, always wondering what he meant. But it does mean satan is active in the world acting against christians.
Right, there is a spiritual battle going on that is constantly referenced, not only in the New Testament but in various parts of the Old Testament as well. Lots of the visions of Daniel, in chapters 7 to 12, for example, have to do with spiritual warfare going on behind the scenes of political events. Also in the beginning of the book of Job, we see a spiritual conflict unfolding behind the scenes, caused by satan, as the cause of what happened to Job. Again as a reference to spiritual warfare, in 2 Kings 6:16-17 Elijah causes a man to see a vision of angelic hosts, which he sees as horses and chariots of fire. The chariots are seen to be protecting the armies of Israel. In Matthew 26:53 Jesus refers to the fact that if he wants to, he can summon twelve legions of angels. In Acts 13:2 and Acts 16:6, the Holy Spirit is said to be directly ordering the actions of the apostles. Everything Paul says about spiritual warfare seems to line up with this groundwork, of which the above are a few examples. And what it says in the book of Revelation at the very end of the Bible also fits into this same framework - there are a lot of parallels between it and Old Testament prophecies as well.
>And if satan can offer jesus all the kingdoms of the world in the temptation, does that make satan the king of the phyiscal world?
It seems so. Jesus refers to him as the "prince of this world" (ὁ τοῦ κόσμου τούτου ἄρχων) in John 14:30. Similarly Paul called this entity "the god of this world" (ὁ θεὸς τοῦ αἰῶνος τούτου) in 2 Corinthians 4:4.
At one point in the epistle of 1 John, this entity is contrasted with Christ in us, where he writes, "greater is he that is in you, than he that is in the world." (1 John 4:4). Overall this shows that the spirit of this world is opposed to Christianity.
