Jhn 8:34 Jesus answered them, "Truly, truly, I say to you, every one who commits sin is a slave to sin.

Jhn 8:35 The slave does not continue in the house for ever; the son continues for ever.

Jhn 8:36 So if the Son makes you free, you will be free indeed.

Since we are in Christ forever, we have freedom that those who are unsaved are without. With that freedom comes an authority as sons and daughters of God.
