It is quite easy to look at the world around us and be discouraged. Because the darkness is increasing.
The ever-changing world around us does not change who God is and what he calls us to do.
Regardless of how the Supreme Court rules on same-sex marriage, abortion, immigration, or any other issues, God remains sovereign.
I heard a wonderful sermon recently. The speaker said something like; "As the darkness around us gets darker, the light inside us shines brighter." And I love that. Because it's true. God is still sovereign, and no matter what happens to the world around us, God remains the same. The darkness around us gets darker, but we carry inside us the Light of our risen Lord. And He is sovereign. No matter what.
