Be afraid...
To me yes these things are going to happen. Prophecy will certainly be fulfilled. However, if a person does the best they can, to live as God wants-ie following the teachings of Christ to the best of our ability- that puts a person in a position of spiritual safety.
Now do I want to live when the Savior comes again? Yes- that would really be something. Do I want to live to see and perhaps survive the evil that will be here beforehand? Not so much.
But we are living in momentous times. So best we be prepared as much as we can be.
Regardless of how we live our lives, we still fall short in the eyes of God. Jesus Christ came to this earth for the sole purpose of taking on our sins and dying with them.
Salvation is a gift of God that can not be earned or bought. We can not take credit for any of our salvation, it is attained through faith in Jesus Christ and that faith is a gift from the Holy Spirit.
Good works are a result of this gift, but not a reason for salvation.
God bless
