HELPS Word-studies

Topical Lexicon
Definition and Scope of Healing

Ἰάομαι encompasses restoration of bodily health, deliverance from demonic oppression, mending of broken hearts, and the ultimate curing of sin’s damage. It never appears as a mere medical term; healing is portrayed as God’s gracious intervention that reaches both body and soul, reversing the curse introduced in Genesis 3.

Old Testament Background

The Septuagint frequently employs ἰάομαι for Yahweh’s covenant mercy (for example, Exodus 15:26; Psalm 103:3; Isaiah 53:5). This backdrop prepares the reader to see in Jesus the promised physician who would take up Israel’s sicknesses and carry her pains.

Healing in the Ministry of Jesus

• Programmatic text (Luke 4:18) – At Nazareth Jesus announces that the Spirit has empowered Him “to heal the brokenhearted,” linking ἰάομαι with the year of Jubilee freedom.
• Representative miracles (Luke 5:17; Mark 5:29; Luke 6:19; 7:7; 8:47; 9:42; 14:4; 17:15; 22:51) display effortless authority: a word, a touch, even the hem of His garment transmits life.
• Comprehensive compassion (Luke 9:11) – “He healed those who needed healing,” underscoring availability to all who come.
• Messianic authentication (Matthew 8:13; 15:28) – Gentile and Jewish petitioners alike discover that distance, time, gender, or ethnicity impose no barrier.

Faith, Forgiveness, and Wholeness

Healing scenes intertwine with faith (Matthew 8:8–13; 15:28) and forgiveness (compare Mark 2:5-12 where σῴζω complements ἰάομαι). Wholeness is never reduced to symptom relief; it signifies reconciliation with God and reintegration into community worship (Luke 17:11-19).

Modes and Means

• Word of command (Luke 7:7).
• Physical contact (Luke 22:51).
• Mediated through disciples (Luke 9:2; Acts 9:34).
• Accompanied by prayer and anointing (James 5:14-16).

The variety highlights divine sovereignty rather than technique.

Apostolic Continuation

Acts records the risen Christ healing through His servants:
• Peter in Lydda – “Aeneas… Jesus Christ heals you” (Acts 9:34).
• Paul on Malta – “Paul went in to see him and prayed, placed his hands on him, and healed him” (Acts 28:8).
• Programmatic summary (Acts 10:38) – Jesus “went around doing good and healing all who were oppressed by the devil.” Luke’s threefold Isaiah citation (Matthew 13:15; John 12:40; Acts 28:27) warns that hardness of heart blocks both hearing and healing.

Healing and the Cross

1 Peter 2:24 applies Isaiah 53:5 to the atonement: “By His stripes you were healed.” The verb points to a completed fact; spiritual cure is already secured for believers, awaiting full bodily manifestation (Romans 8:23).

Pastoral Application

James 5:16 urges confession and intercession “so that you may be healed,” preserving healing within the ordinary life of the church. Hebrews 12:13 exhorts disciplined perseverance lest crippling discouragement overcome believers: “rather, be healed.” Physical or spiritual, the remedy lies in drawing near to the throne of grace.

Eschatological Hope

Present healings are signs, not consummation. Revelation anticipates the tree whose leaves are “for the healing of the nations” (Revelation 22:2, using a cognate term). Every temporal cure foreshadows resurrection bodies where ἰάομαι’s work is perfected and irreversible.

Related Concepts

σῴζω (to save), θεραπεύω (to serve, cure), ὑγιαίνω (to be sound) converge with ἰάομαι to reveal salvation’s holistic reach. Together they proclaim that in Christ the Creator is actively reclaiming His fallen creation.
