He who does what is sinful is of the devil, because the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the devil’s work.
Job 8:9
We were born only yesterday and know nothing, and our days on earth are but a shadow.
1 Thessalonians 4:11-12
Make it your ambition to lead a quiet life, to mind your own business and to work with your hands, just as we told you, so that your daily life may win the respect of outsiders and so that you will not be dependent on anybody.
