free (man, woman), at liberty

Concise Bible Dictionary:

Besides the common application of this term, it is used in scripture symbolically, as
1. The liberty obtained by Christ for those that were captives of Satan (Isa. 61:1; Luke 4:18; John 8:36).
2. The conscience set free from guilt, as when the Lord said to several, “Thy sins be forgiven thee: go in peace.”
3. Freedom from the law, “Stand fast therefore in the liberty wherewith Christ hath made us free” (Rom. 7:24-25; Gal. 5:1). Jesus said, “I am the door: by me if any man enter in he shall be saved, and shall go in and out, and find pasture” (John 10:9).
4. The Christian’s deliverance from the power of sin by having died with Christ, as in Romans 6:8-22; and, having reckoned himself dead to sin, experimentally enjoying liberty, as in Romans 8:2-4, after experiencing that the flesh is too strong for him. The deliverance is realized by the Spirit of life in Christ Jesus, and the love of God is known and enjoyed. Christ is then the object before the soul, and not self.
