Amen, brother!
I believe the spiritual danger increased after the Crucifixion because the evil one knows he's running out of time and has failed. Also, I think a great many Christians don't fully understand the significance of a bodily resurrection. In the Hellenistic culture of the Roman Empire spirits appeared all the time, but they were just that spirits. I see no reason to believe they've stopped and as you believe they have attempted to attack me on numerous occasions, just as you gave the example of with the distraction while in church.
I think your right about discernment, but I also believe I am right that the LORD only sent humans to Earth once. Thus, the discernment we need for this is provided in what we all should be striving to study, Scripture.

Ah, how excellent of you! One of my favorite saints, the holy +Seraphim of Sarov taught:
"It is very useful to spend time reading the word of God in solitude and to read the whole Bible with understanding. In return for this exercise alone, without the addition of any other virtuous deeds, the Lord grants man His mercy and fills him with the gift of understanding. When a man provides his soul with the word of God, then he is granted the understanding of what is good and what is evil."
