Passage Texts

Isaiah 45:24: “Surely they will say of Me, ‘In the LORD alone are righteousness and strength.’ ”

Philippians 4:13: “I can do all things through Christ who gives me strength.”

Same Source, Different Covenants

• Isaiah points Israel to the LORD (“YHWH”) as the exclusive well of “righteousness and strength.”

• Paul points believers to Christ as the same well of “strength.”

• The New Testament identifies Jesus as the LORD made flesh (John 1:1–14; Colossians 1:15–17).

➔ The very strength Isaiah ascribes to YHWH is the strength Paul experiences in Christ.

What Isaiah Emphasizes about Strength

• Exclusivity: strength is “in the LORD alone,” not in idols, rulers, or self-effort.

• Righteousness and strength are inseparable gifts from God; moral standing and power flow together.

• Universal submission: “All who rage against Him will come to Him and be put to shame” (v. 24b), showing His unmatched authority.

What Paul Emphasizes about Strength

• Personal union: “through Christ” implies an intimate, indwelling relationship (Galatians 2:20).

• Practical sufficiency: “all things” covers every circumstance—plenty or need (Philippians 4:11-12).

• Ongoing supply: “gives me strength” (present tense) signals continual empowerment (2 Corinthians 9:8).

Key Points of Connection

• One Giver: Isaiah calls Him “the LORD”; Paul names Him “Christ.” Same divine Person, same power.

• From declaration to experience: Isaiah foretells; Paul testifies.

• Covenant continuity: Strength promised to Israel’s remnant (Isaiah) is realized in the church (Philippians).

• Righteousness + strength: In both texts, God never grants power without holiness (compare 2 Corinthians 12:9; 2 Peter 1:3).

Living Out the Truth Today

1. Rest in His exclusivity—refuse counterfeit sources of worth or power (Jeremiah 17:5-8).

2. Receive His righteousness—accept the completed work of Christ (Romans 3:22-24).

3. Rely on His present strength—approach every task, trial, or temptation with “through Christ” on your lips (Ephesians 6:10).

4. Rejoice in His certainty—Isaiah’s prophetic certainty (“Surely…”) anchors Paul’s confident “I can” (Hebrews 13:8).

Supporting Scriptures for Further Reflection

• Psalm 18:1-2 — “The LORD is my strength.”

• John 15:5 — “Apart from Me you can do nothing.”

• 2 Corinthians 12:9-10 — “My power is perfected in weakness.”

• Colossians 1:11 — “Strengthened with all power according to His glorious might.”
