I'm going to be very blunt. Should the era we live in concern us? YES.
The Holy Spirit is putting out a world wide "wake up" call and very few are heeding it. There really is no need to "discern the times". It is written, as clear as a bell, everywhere we look. One would have to be completely blind spiritually not to see the writing upon the wall at this point.
Despite the clarity of the picture around us, God, in his goodness, is going to allow this picture to become even clearer. The demarcation lines between good and evil will continue to grow greater and soon no one will be able to walk between these two lines but will choose one or the other. There will be no middle ground.
I have written about this in the past and in no way has this sense of the "spiritual emergency" our world is facing lessened. If anything it has grown stronger.
We should pray daily to the Holy Spirit for the light of His truth to pierce the darkness of our times and for the grace to stand firm in our faith despite the obstacles around us. In this way we can become "little beacons of light" for others.
