population is variable and movable...people can and do migrate to where they can raise their young and if conditions are favaourable, they will, if not, its much harder. Chrstians are not concerned with left or right politics...well they shouldnt be.
Salavtion of souls is a lot more important. When the egyptians tried to control the Hebrew population, God let them cross the red sea into the promised land and got them through the plagues.Then when they inherited the promised land, if they fell into idolatry, they got scattered and exiled.
Do we not learn anything through what Jesus taught us?
God knows we should not worry about what we shall eat or drink, those are worldy concerns. He provides for the sparrows, He cares for us. If we first seek His kingdom and his righteousness, everything will be added unto us.
