A spiritual monster!

(Thomas Boston, "Human Nature in its Fourfold State")

The unrenewed man's affections are wholly corrupted,
disordered and distempered. Man's heart naturally is
a mother of abominations! "For from within, out of
men's hearts, come evil thoughts, sexual immorality,
theft, murder, adultery, greed, malice, deceit, lewdness,
envy, slander, arrogance and folly." Mark 7:21, 22

"Men loved darkness." John 3:19

The natural man's affections are wretchedly misplaced.
He is a spiritual monster!

His heart is where his feet should be—fixed on the earth.
 
His heels are lifted up against heaven—which his heart
should be set on.

His face is towards hell; his back is towards heaven.

He loves what he should hate; and hates what he should love.

He joys in what he ought to mourn for; and mourns for
what he should rejoice in.

He abhors what he should desire; and desires what
he should abhor.

"Lovers of pleasure rather than lovers of God." 2 Tim. 3:4
