In Romans 5:3-4, the chain that begins with suffering ends with what?

Answer: Hope

Suffering produces perseverance, perseverance character, and character hope (KJV: tribulation, patience, experience, hope).

“Not only that, but we also rejoice in our sufferings, because we know that suffering produces perseverance; perseverance, character; and character, hope. And hope does not disappoint us, because God has poured out His love into our hearts through the Holy Spirit, whom He has given us.”— Romans 5:3-5 (BSB)
