How do I restrict the activities of Satanic forces around the teaching of the Word Of God?

I point you to the 'Parable of the Sower' in three of the Gospels and to 2 Corinthians 4:4. These scriptures make it clear to us that, whenever the Word Of God is preached or taught, Satan gets involved in the following ways: 1) He will immediately steal the seed of the Word if the receiving heart is 'hard ground'. 2) He will bring persecution and affliction for the Word's sake if the receiving heart is 'stony ground'. 3) He blinds the minds of unbelievers, lest the light of the Glorious Gospel should shine unto them. (2 Corinthians 4:4) It is my belief that a Christian can 'bind Satan' in these teaching situations when the Christian acts in the Name of Jesus and that Satan must then desist in his manoeuvres. My question is, "Can a Christian 'bind Satan' in the Name of Jesus in a prayer that is recorded in the video lesson that can be played to different audiences at different times and all over the world?" **or** Must the Christian be present at the time that the teaching is taking place, in order to be able to 'bind Satan' in this situation in the Name of Jesus?
