“But solid food is for the mature, who by constant use have trained themselves to distinguish good from evil.” – Hebrews 5:14 NIV

It is extremely dangerous to not be able to distinguish between good and evil because it is difficult to tell whether or not an action will be helpful or harmful before you take it. You can attempt to help someone and do them great harm by your advice or works to help. We need to be thoroughly equipped with God’s word to know what to do and when to do it to be able to keep ourselves from unintentionally doing harm to ourselves or others.
