"There'll be a golden ladder reaching down"
"So while he's warning of the judgement to come, Cash is pointing to the way out of the horrible fate he's described, from the book of Genesis":
As [Jacob] slept, he dreamed of a stairway that reached from the earth up to heaven. And he saw the angels of God going up and down the stairway.
Gen 28:12

"When the Man comes around"
"Cash's song title comes at the end of each section of the song. He's referring to Jesus' return to Earth at the time of judgement, which is mentioned throughout the Bible, including this vision the Old Testament, which Jesus later said was referring to himself":
I saw someone like a son of man coming with the clouds of heaven. He approached the Ancient One [God] and was led into his presence. He was given authority, honour, and sovereignty over all the nations of the world, so that people of every race and nation and language would obey him. His rule is eternal-it will never end. His kingdom will never be destroyed.
Daniel 7:13-14

"The hairs on your arm will stand up"
"Cash continues to paint a picture of a frightening time, which Revelation also makes clear":
Then everyone-the kings of the earth, the rulers, the generals, the wealthy, the powerful, and every slave and free person-all hid themselves in the caves and among the rocks of the mountains. And they cried to the mountains and the rocks, "Fall on us and hide us from the face of the one who sits on the throne and from the wrath of the Lamb. For the great day of their wrath has come, and who is able to survive?
Revelation 6:15-17
