Topical Lexicon Canonical ScopeStrong’s 950 underlies eight passages in the Greek New Testament, clustering in the Gospels, Pauline writings, and Hebrews. In every setting the verb highlights God’s action of rendering something firm, reliable, and unassailable, thereby safeguarding the gospel, confirming covenant promises, and securing believers for persevering witness and holy living. Foundation in God’s Covenantal Faithfulness Romans 15:8 links the confirming work to the patriarchal promises: “For I tell you that Christ has become a servant of the circumcised on behalf of God’s truth, to confirm the promises made to the patriarchs”. The Old Testament commitments of God never waver; they are given final, public attestation in Jesus Christ. The verb underscores that the Abrahamic and Davidic covenants are not merely honored but rendered incontestable in the incarnate Son. Christ, the Divine Confirmer 2 Corinthians 1:21–22 places the verb at the center of Trinitarian salvation: “Now it is God who establishes us with you in Christ and has anointed us, placed His seal on us, and put His Spirit in our hearts as a pledge”. The confirming activity is both Christocentric and relational—believers are stabilized “with you,” knitting Paul, his co-workers, and the Corinthian church into a single Spirit-sealed fellowship. 1 Corinthians 1:6 and 1:8 present an eschatological horizon. The testimony concerning Christ “was confirmed in you” (1:6), and on the Last Day Christ Himself “will sustain you to the end, blameless in the day of our Lord Jesus Christ” (1:8). The initial establishment of the gospel in the church and its ultimate vindication before the judgment seat form one unbroken continuum. Apostolic Authentication Mark 16:20 shows the original missionary setting: “And they went out and preached everywhere, and the Lord worked through them, confirming the word by the signs that accompanied it”. Hebrews 2:3 echoes the same principle—salvation “was first announced by the Lord, was confirmed to us by those who heard Him.” Divine confirmation validates apostolic proclamation through signs, wonders, and Spirit-empowered witness, leaving hearers without excuse. Stability in Christian Discipleship Colossians 2:7 exhorts believers to continue “rooted and built up in Him, established in the faith as you were taught, and overflowing with thankfulness”. Here the verb describes the day-to-day fortifying of the believer’s walk, grounding head and heart in a tradition received from faithful teachers. Hebrews 13:9 warns, “Do not be carried away by all kinds of strange teachings. For it is good for our hearts to be strengthened by grace”. The variant renderings “confirmed” or “strengthened” indicate that God’s grace, not speculative doctrines, secures the inner life. The Holy Spirit’s Sealing Work Three passages (2 Corinthians 1:21, Romans 15:8, Colossians 2:7) frame confirmation as the Spirit’s seal. The Spirit applies the objective work of Christ to subjective assurance, engraving divine ownership and enabling persevering obedience. Historical Reception Early Church writers drew pastoral lines from these texts. Irenaeus argued that post-apostolic miracles continued to confirm the same gospel preached by the apostles (Against Heresies 2.32.4). Tertullian cited Hebrews 2:3 against Montanist critics, asserting that authentic prophecy maintains continuity with the message once “confirmed” by apostolic witnesses. Augustine applied 1 Corinthians 1:8 to the doctrine of perseverance, contending that the same God who elects also confirms believers until the end. Doctrinal and Practical Implications 1. Assurance: God Himself guarantees the believer’s standing; subjective feelings yield to objective confirmation in Christ. In sum, Strong’s 950 traces a golden thread from patriarchal promise to eschatological fulfillment. The God who binds Himself by oath is the God who, in Christ and by the Spirit, irrevocably confirms His word, His servants, and His people.
