Albert Barnes Commentary John 8:36

"If therefore the Son shall make you free, ye shall be free indeed." — John 8:36 (ASV)

If the Son, and so forth. The Son of God—heir of all things—who is forever with God, and who has therefore the right and power to liberate men from their bondage.

Shall make you free. Shall deliver you from the bondage and dominion of sin.

Free indeed. Truly and really free. You will be blessed with the most valuable freedom; not from the chains and oppressions of earthly masters and monarchs, but from the bondage of sin.
