If Christianity is only one more bit of good advice, then Christianity is of no importance.
Think of me as a fellow patient in the same hospital who, having been admitted a little earlier could give some advice.
To have Faith in Christ means, of course, trying to do all that He says. There would be no sense in saying you trusted a person if you would not take his advice.
As a Christian I take it for granted that human history will some day end; and I am offering Omniscience no advice as to the best date for that consummation.
But in general, take my advice, when you meet anything that is going to be Human and isn’t yet, or used to be Human once and isn’t now, or ought to be Human and isn’t, you keep your eyes on it and feel for your hatchet.
