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!"
Neglecting to do right is as sinful as doing wrong. It's in the Bible, James 4:17, TLB. "Remember, too, that knowing what is right to do and then not doing it is sin."
