Freedom

Galatians 5:13-14 NASB
13 For you were called to freedom, brethren; only do not turn your freedom into an opportunity for the flesh, but through love serve one another.
14 For the whole law is fulfilled in one word, in the statement, "YOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF."

This morning I was curious about "freedom." Exactly what did Paul mean by using that word? So, I turned to "freedom" in Strong's and found that it's used twice in the entire KJV Bible, but not in Galatians 5:13. I looked up Galatians 5:13 in my King James Version and saw that it used "liberty" instead of "freedom." I looked up "liberty" in Strong's. For this verse, it's #G1657, and that corresponds to the Greek word "eleutheria," which means "freedom," legitimate or licentious, chiefly moral or ceremonially.

After reading that definition, I saw why it was so important for Paul to add that last part of verse 13--to make sure that his readers knew exactly what kind of freedom he was talking about.
For what did Paul want them to use their freedom?
And if somewhere really were interested in keeping the law, what is the essence of the law?

In thinking about freedom being liberty from moral and ceremonial laws, which is what God's law is, what strikes you about what Paul is saying in these two verses?
If they truly love their neighbors as themselves, would they need an external written law?
