How do dispensationalists reconcile their view with these passages that appear to teach a single, unified gospel?

Dispensationalism is often understood to distinguish between God’s plan for Israel and for the Church, and some formulations suggest differences in how the gospel is administered or understood across dispensations. However, several biblical passages seem to emphasize a single, unified gospel message and consistent basis for salvation: - Galatians 1:8–9 — Paul warns against “another gospel,” strongly affirming that there is only one true gospel. - Ephesians 4:4–6 — speaks of “one body… one Lord, one faith, one baptism.” - Acts 10:43 — Peter declares that “everyone who believes in Him receives forgiveness of sins through His name.” - Romans 3:22–30 — emphasizes justification by faith for both Jews and Gentiles, with God being “one.” - John 3:16 — presents belief in Christ as the basis for eternal life universally. Given these passages, how do dispensationalists interpret texts that emphasize a single gospel and unified means of salvation? Do they understand these verses as applying universally across all dispensations, or do they interpret them within a specific dispensational context?
