Psalm 5:8: Lead me, Lord, in your righteousness, because of my enemies; make your way straight before my face.
What is the best way to make something you have never made before? Is it not to follow the instructions of someone who has made that before?
Recipe books are there so others can learn how to make or cook new foods. Medical journals are there for doctors and nurses to be able to help more sick people.
The bible is here for us to learn from and to follow. All of the above are not just suggestions of how to do things but instruction methods for us to get it right!
It is up to you whether you follow the instruction of those who have gone before us or make things up for yourself.
