He's good all the time and all the time He is good.
He wants to use our life as a testimony to people not to ever give up -- to stay with Him during the tough times and during the great times. Yes, He's good and He ensures "we will not fear though the earth gives way, though the mountains be moved into the heart of the sea, though its waters roar and foam, though the mountains tremble at its swelling (Psalm 46:2/3). He reminds us that we have nothing to fear. Fear (or anxiety) don't come from the Lord. Relax in Him and take solace that His Word stands through the test of time. It's solid, credible, and reliable. If you're having some challenges and going through a hard time right now, keep praying to God and keep seeking Him. And if you're not going through a hard time, still pray and keep seeking Him.
