(Proverbs 23:10 KJV) Remove not the old landmark; and enter not into the fields of the fatherless:
Tradition is a powerful force. Some boundaries in our culture are based on tradition. Just because we don’t understand them does not mean they are useless. For us this is referring to basics, the foundation stones that we build on. This is not talking about the shifts and trends that we see every day.
Think about the “old” (ancient NASB) (5769) standards that are under attack. We had social norms that defined marriage and family. We had an understanding that there is only one way to salvation, through Jesus. We were brought up to believe that the animals were for our use not that they were our brothers. Children were works in progress, not sources of wisdom.
Most of these standards can be easily documented in the Word. If you are not aware of that you have not been serious about your homework.
So? You can’t tell you are drifting if you don’t know the landmarks. You won’t notice if you are not paying attention. Do you know what God has to say about these things or do you just know what some guru has shared with you?
