The Greek verb eleutheroō means to set free or liberate — releasing someone from slavery, bondage, constraint, or obligation. Derived from eleutheros (free), it is one of the key New Testament words for spiritual liberation, standing at the center of Paul's theology of redemption.
Eleutheroō is the word behind Jesus's magnificent promise: 'If the Son sets you free, you will be free indeed' (John 8:36). Paul uses it repeatedly in Romans 6-8: freed from sin (6:18,22), freed from the law of sin and death (8:2). This is not freedom from all constraint but freedom from slavery — the transfer from bondage to sin into the glorious freedom of the children of God (Rom 8:21). Galatians 5:1 commands: 'It is for freedom that Christ has set us free. Stand firm, then, and do not let yourselves be burdened again by a yoke of slavery.' True freedom in Christ is found not in casting off all authority but in gladly submitting to the Father.
