Corruption; Lusts; Deceits
A Sermon on Ephesians 4:22-24
to put off your old self, which belongs to your former manner of life and is corrupt through deceitful desires, and to be renewed in the spirit of your minds, and to put on the new self, created after the likeness of God in true righteousness and holiness. (ESV)
There is no 'Peter Pan' theory in the Bible : man is born corrupt; the non-Christian life is one of decay and putrefying; man and his instincts; the matter of sex; the subtlety of the devil; the deceitfulness of sin; sin discourages; sin is entirely destructive.
