It all depends on your perspective, from where you come and where you want to go.
If you want to bolt from Christianity, the gateway bears the title: “The Gates to Hell.” But if you are already in the life of hellishness and you want to escape to Christianity, the headpost declares: “The Gates of Righteousness.” But it is the same doorway.
Either you exit godliness or you exit godlessness. Either you enter the world and the wide path that leads to destruction, or you enter salvation by grace and continuing a walk with Christ that leads to blessing and Heaven. But it is the same doorway by which some enter and others leave.
