Can an
"αιων" [aiwn, aeon, in either time, distance or space] come to an end? Yes, even as Paul shows in Hebrews:
Hebrew 9:26 KJB - For then must he often have suffered since the foundation of the world: but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself.
Hebrew 9:26 KJB - επει εδει αυτον πολλακις παθειν απο καταβολης κοσμου νυν δε απαξ επι συντελεια των αιωνων εις αθετησιν αμαρτιας δια της θυσιας αυτου πεφανερωται
Notice,
"end of the world [aeon]". Notice again:
Titus 2:12 KJB - Teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly, in this present world;
Titus 2:12 KJB - παιδευουσα ημας ινα αρνησαμενοι την ασεβειαν και τας κοσμικας επιθυμιας σωφρονως και δικαιως και ευσεβως ζησωμεν εν τω νυν αιωνι
Notice,
"in this present world [aeon]", which indicates that there is an end to the current
"world", or existence, and another
"world" [aeon], or existence, to follow after it. Thus and
"aeon" can come to an end, and is not necessarily eternal. See also
"since the world began",
"before this world",
"this present evil world",
"this world", in Matthew 12:32, Matthew 13:22, Matthew 13:39-40 (2), Matthew 13:49, Matthew 24:3, Matthew 28:20, Mark 4:19, Mark 10:30, Luke 1:70, Luke 16:8, Luke 18:30, Luke 20:34-35 (2), John 9:32, Acts 3:21, Acts 15:18, Romans 12:2, 1 Corinthians 1:20, 1 Corinthians 2:6-8 (4), 1 Corinthians 3:18, 1 Corinthians 8:13, 1 Corinthians 10:11, 2 Corinthians 4:4, Galatians 1:4, Ephesians 1:21, Ephesians 3:9, Ephesians 3:21, Ephesians 6:12, 1 Timothy 6:17, 2 Timothy 4:10, Tit 2:12, Hebrews 6:5, Hebrews 9:26; and etc. We now see that
"aeon's" can begin, and end, and are not always ongoing without ceasing, and thus context always determines the length, distance, existence, etc.
