What is your ultimate authority for making important decisions? Is it your knowledge? Intuition? Your experience? is it people you want to please? Is it contemporary culture? Is it a synagogue, church, or certain spiritual leader?
I want to suggest God’s Word. God has created you for a purpose. He knows how you work best. The way He speaks through His written Word, and it is perfectly true. It applies to every age, race, and nation.
The Bible is clear on some things like murder, stealing, adultery, and forgiveness. When it doesn’t speak to a specific issue–like which mutual funds to invest in, whom to marry, or stem cell research, it gives perfect principles we need to know in order to make the best decisions–those that are pleasing to God.
So try reading it. Start with the New Testament. Ask God to speak to you through His Word. When it comes to living well, God’s Word knows best.
