Now another way to do a word study is to take a portion of scripture and trace the words within that passage.
I am looking at Chapter 0ne verses 18 through 20:
For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men who suppress the truth in unrighteousness because that which is known about God is evident within them; for God made it evident to them. For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse. NASB
You ask questions of this. How is God known? What is evident? What is the unrighteousness talked about?
Use the book. You have been reading through Romans a few times and by now have an idea of that is in it.
Dig. Use a concordence which will give you each time the word is used.Jot down what you are finding in your journal or that notebook you are keeping for this study.
This takes time. I am not talking about a short devotional time. This is work. But it is worth it.
Please feel free to leave comments so I will know how I am doing.
