Neglecting God and his Word can undermine all of life. It's in the Bible, Matthew 7:26, TLB. "But those who hear My instructions and ignore them are foolish, like a man who builds his house on sand."
Neglecting God's commands is disobedience to God. It's in the Bible, Mark 7:9, NIV. "And he said to them: 'You have a fine way of setting aside the commands of God in order to observe your own traditions!"
