We have ONE "BOTH, noone has ever achieved it. "
One, "It is a process, and you can't know for certain until you die and are judged by the Lord. However, you can have a pretty good assurance, but you can't ever assume you are righteous enough."
And one, "I believe we can be reasonably assured that we will see Heaven upon our death if we walk firmly in Christ, holding firmly to that inheritance that is ours through Christ. but since rejection of the grace we have been given is always possible, we cannot be certain of future actions/dispositions of ours. "
