Types of Enemy Attacks
Preaching is not just about delivering God's Word to the people, but it is a full-on war in the spiritual realm against Satan, as stated in:
For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.
Satan knows those who are truly anointed by God to preach, and he works his hardest to stop you from being effective. He also knows what buttons of yours to push, he knows what your weaknesses are, he knows what will get you annoyed, and he will use these to get to you. By being aware of his attacks, you can learn to overcome him. Satan will attack you before, during and after your sermon. He tries to catch you off guard, but there are only so many tricks that he can do, so if you can be aware of as many of his tricks as possible, he stands little or no chance of causing havoc. Here is a list of the attacks to watch out for that I have experienced first-hand; these may come any time before, during, or after a sermon.
