The Greek noun hupomone (ὑπομονή) means steadfast endurance, perseverance, or patient continuance under pressure. It derives from hupo (under) + meno (remain) — to remain under the weight. It appears about 32 times in the NT.
Hupomone is one of the NT's great virtue words — the quality that keeps a believer faithful through suffering, opposition, and delay. Unlike the English 'patience' (which suggests passive waiting), hupomone is active — it is the marathon runner pressing on, the soldier holding position under fire. Romans 5:3–4 traces the spiritual genealogy: 'suffering produces hupomone, and hupomone produces character, and character produces hope.' The Revelation letters invoke hupomone as the hallmark of faithful churches (Revelation 1:9; 2:2, 3, 19; 3:10; 13:10; 14:12). Hebrews 12:1 calls believers to 'run with hupomone the race marked out for us' — keeping eyes fixed on Jesus who 'for the joy set before him endured the cross.' Hupomone is faith in time — it is what love looks like when tested.
