A sure way to go to hell is by living and dying without any religion at all. You may live like a beast, prayerless, godless, graceless and faithless. This is a sure way to go to hell.
Another way to go to hell is by taking up some kind of useless religion. You can live and die contenting yourself with a false christianity and rest on a groundless hope. This is probably the most common way to hell that there is today. There are many ways to hell, but only one way to heaven.
A religion is useless in which Jesus Christ is not the principle object. Most people today know nothing about Christ. Their religion is a few vague notions and empty expressions. They say, "I am no worse than others. I go to church when it is convenient. I really don't do anybody any harm. I hope God will be merciful to me." But He won't! God shows no mercy apart from His Son.
