Hopefully making theology simpler to understand! (2 Corinthians 1:12)

Live as people who are free, not using your freedom as a cover-up for evil, but living as servants of God.
1 Peter 2:16 ESV

Freedom is the ability to choose. We are free to choose sin (from which we have been freed), but why would we want to use our freedom to slap God in the face rather than love Him?
