Yeshua uses unmistakably graphic language to describe Hell. (Mk 9:43-44, 45-46, 47-48) He’s warning us to do all we can to avoid it. Who among us will go there? (Is 33:14) What would it be like do die the second death?
The Lake of Fire is the dreadful fate of all who fail to find their eternal home in Christ. (Re 21:8) Fear of spending eternity in Hell drives the wise to ensure their election, until they’re as sure of Heaven as Christ Himself. Take no chances: perfect assurance of eternal salvation is available; nothing less is acceptable.
Only a few diligently secure their place in Heaven; whatever it takes, strive to enter: be one of them. (Mt 7:13)
