God is good all the time. All the time, God is good. Not some of the time, not most of the time. ALL the time. Meditate on that and you will be changed!
Even though we live in a world filled with sadness and sin, we have hope. God is our hope. He is so good. He gives us shelter from this world. He can take us in and love us with His perfect love. The world may hurt us, but God is good and we can rest in that.
