God decides who is saved and who is not, correct?
Then no one knows if they are saved unless God has spoken to them DIRECTLY and said as much.
Philip wrote: Of COURSE, one can know! IF they have truly done what Scripture teaches one MUST do to be saved, then they ARE saved. Period! And yes, God DID communicate to us through Scripture - it is living and active - so I'd also call that also speaking to us directly. IF one could not know whether or not they are saved, then we could have NO confidence of that, and we would be forced to live in fear and constantly at the mercy of our feelings of how our "supposed" salvation feels - or doesn't feel - at any given moment. Can we know for certain whether another is saved or not - I'd say no - because we can't see their hearts and minds. We can only look at their fruit and discern probabilities based upon that. But we could be wrong. But we know our OWN hearts and minds and the truth of whether we have truly believed and committed our lives into His hands, placed our trust in Him.
Paul Wrote: OH, so as long as we DO what we MUST to be saved, we ARE saved, eh?
Yes!
Romans 10:9 "because, IF
you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead,
you will be saved. 10 For with the heart one believes and is justified, and with the mouth one confesses and is saved."
So, Scripture tells us if we "DO" the above, we will be saved. But one cannot truly DO the above unless he truly believes what this verse tells us we must - AND the verbal confession must match what is truly in the heart.
Similarly: "“Believe in the Lord Jesus, and you will be saved, you and your household.” (Acts 16:31)
So, YES, what we DO is important to our salvation (as is the absence of doing so) - but this is not a "work" or in any way earning it. It is a mere acceptance of what has been provided, paid for, and offered us. And so Scripture teaches if we have sincerely confessed, BELIEVED and committed ourselves to Jesus, we ARE saved. Of course, as we could have done none of this without the Lord FIRST making it possible, so it is FIRST what the Lord did, but also we DO what He has said we must do to RECEIVE what HE has done.
