Romans 5:3-4 — And not only so, but we glory in tribulations also: knowing that tribulation worketh patience.
And patience, experience; and experience, hope.
Glory (in this verse) = rejoice
Patience — not passive, the ability to remain strong while bearing the burden of tribulation.
We rejoice in the ability to endure. For unbelievers, happiness here is all they have, so tribulations rob them of everything.
Experience = consciousness of having endured tribulation effectually which is proof of the presence of the Holy Spirit. This proof encourages us in hope.
