In verse 17, God makes it clear that Adam is being punished because he listened to Eve instead of to God. This shows us the need to reject peer pressure, even as adults, and to live to please God rather than people. It shows the need to reject other people's ideas and advice, just as Adam should have with Eve, when they contradict God's known will.
Who has your ear? What person do you listen to
most in your life? When you have a decision to make, do you go to them
before you go to God?
Remember that every person is
fallible, despite their intentions, and that only God will lead us right
every time. Go to Him first and reject any suggestions that contradict
what you feel He's telling you either in Scripture or in prayer.
