"and if not, He is still good" is based on Daniel 3:18 when Shadrach, Meshach, and Abednego are responding to King Nebuchadnezzar. In this moment, the three men are basically telling King Nebuchadnezzar that he can save his threats because God is bigger and can rescue them from anything the king could do to them. More than that, though, they say, even if God did not rescue them, HE is still good and they would do nothing different. They would still make the choice to serve God in spite of the threats of Nebuchadnezzar or the potential consequences.
"and if not, He is still good" has been with me many days in the last few seasons of my life. This past year has been amazing and difficult all at the same time. I have faced disappointments when my expectations did not line up with my reality. I have faced betrayals of people I allowed into my closest circle. I have faced friends and loved ones deal with life-threatening illnesses. I have walked through the pains, sorrows, and joys of life with my friends and my family, all the while holding most of myself to myself. Holding on to "and if not, He is still good."
So, no matter where you are tonight, just know, "and if not, HE is still good."
