This wonderful, we should not expect same thing every day. Because things are changing everytime.
We should prepare to face many things in life, as you said sometimes thing seems good, going well and beautiful.
But sometimes thing get complicated and hard to bear, but we have to endure.
Because nothing last forever, even bible in Ecclesiastes 3:1-5 that there is time for everything and a season for every thing under the heavens
RE: Not every day is the same, there are good days and there are bad days and we need to be prepared!!!
