"A wise man will hear and increase in learning, And a man of understanding will acquire wise counsel..."
-Proverbs 1:5
Note that it doesn't say that a man of understanding will acquire thoughts or opinions. Nor does it say that he will acquire simply counsel. But a man of understanding will acquire WISE counsel. In a day and age where people are ever more free and comfortable to share their thoughts and opinions, we must be careful about who we are letting speak into our lives.
When making a decision, especially a major decision, it is vital that we know who and what we are being influenced by. If you are a Christian, these decisions should be weighed against two things... the Word of God and your spiritual discernment.
It's good to seek advice and counsel. In fact, Proverbs 15:22 tells us that plans fail due to lack of counsel. However, make sure the counsel you receive is more than just someone's thoughts or opinions.
