This is Jesus talking here in these 2 verses...
29 And everyone who has given up houses
for my sake,
will receive a hundred times as much in return
and will inherit eternal life.
30 But many who are the greatest now will be least important then,
and those who seem least important now will be the greatest then.
Something to remember when the way gets tough,
as we walk the God life of a servant,
following His lead,
& doing what He commands.
