And Peter opening his mouth, said: In very deed I perceive, that God is not a respecter of persons. (Acts 10:34)
God does not show favoritism, and neither should we. We are commanded to love all people, even those who bus tables, who polish the rails, who deliver the mail. (Does it cost anything to smile at someone and say Hello? To acknowledge them and thank them for doing what they do?)
In your life, you will meet many people who will snub you. You're not worth their time and attention. They discount you, try to make you feel small and insignificant. When God elevates you to a new level, these same people will come back and act like they've been your BFF all along. By their fruits ye shall know them. Don't be ugly to them. But don't befriend them. They're opportunists.
We should praise God in the valleys, the hard times. Why? Because He's still giving us an opportunity to learn something very useful:
When you are limping along, you'll learn whom to let ride with you in the limousine.
