On the Jehovah's Witnesses official website, anyone can read all about how to come to be right with God, how God requires us to act, and what God requires us to believe (and do) in order to be saved and live eternally with Him. Or can they?
Of all the questions one can ask in his or her lifetime,
"What". It indicates a thing, an object or duty. Clearly something is the object of this question.
"Must". It is not what can I do, or what may I do, but what must I do. This implies obedience to a command---the only command the sinner can possibly obey.
"I". It is not what God, Christ and/or the Holy Spirit must do. It is what I must do, and no one else can do it on my behalf. All within "Christian" circles are agreed that God, Christ and the Holy Spirit have their roles in every person's salvation: but there is one thing more, one thing that only that person can do.
"Do". The question is not simply what must I mentally agree with, nor what church aisle I must walk down. Some would make it seem that this part of the question involves keeping every single law or command that God wrote in the Bible. Others would say that this question means you can just believe---and then do whatever you want. Neither of these is true, my friend. But what does the Bible say?
"To be saved". It is not "to be sanctified". It is not "to become a member of thus-and-so-church". As far as this basic issue goes, those things are irrelevant. But what can any man do to live and abide in the presence of God?
