I can understand the very human desire for reassurance and for certainty about the future, it is after all what drives people to seek foretelling of events from astrologers and tarot cards and from mediums and fortune tellers so it is no surprise to find Christians seeking to be reassured about their personal future and hence being very keen to find theological justifications for thinking that they know that they are saved, irrevocably and completely and certainly saved with no chance of error and no possibility of loss. But wishing for certainty does not make certainty real.
Romans 8: 18 I consider, that the suffering of our present life cannot be compared with the glory that will be revealed, and given to us. 19 All creation is eagerly expecting the birth, in glory, of the children of God. 20 For, if now, the created world was unable to attain its purpose, this did not come from itself, but from the one who subjected it. But it is not without hope; 21 for even the created world, will be freed from this fate of death, and share the freedom and glory of the children of God. 22 We know, that the whole creation groans and suffers the pangs of birth. 23 Not creation alone, but even ourselves; although the Spirit was given to us, as a foretaste of what we are to receive, we groan in our innermost being, eagerly awaiting the day, when God will give us full rights, and rescue our bodies as well. 24 In hope, we already have salvation. But, if we saw what we hoped for, there would no longer be hope: how can you hope for what is already seen? 25 So, we hope for what we do not see, and we will receive it, through patient hope. 26 Likewise, the Spirit helps us in our weakness; for we do not know how to pray as we ought, but that very Spirit intercedes for us, without words, as if with groans. 27 And he, who sees inner secrets, knows the desires of the Spirit, for he asks for the holy ones, what is pleasing to God.
