“Being saved doesn’t ‘t make one knowledgeable or accurate about Bible Prophecy or even the other doctrines of the Bible.”
But it should make one a disciple of Christ. To be a disciple is to be disciplined, and study is part of the training necessary to be mature in Christ.
Newborn babies are ignorant of virtually everything, yet we don’t expect them to stay that way. Neither did Paul nor the apostles expect the people they brought to salvation in Christ to stay as “babes” in Christ.
There are Christians who are “seasoned” Christian and are disciples of Christ — and even pastors and professors in seminary — who are simply and PLAINLY WRONG.
It doesn’t even have to do with how well studied they are, or how much they are a disciple of Christ — they are STILL WRONG!
I’m afraid it doesn’t quite work the way you’re saying ... unfortunately. So even being diligent and a disciple of Christ, they can be wrong.
That’s why my favorite saying is that accepting Christ as your personal savior doesn’t make you right, but simply saved ... :-) ...
