Although a person getting on a roller coaster ride may be a little fearful, they get on it anyway, because they know that a very smart engineer designed the roller coaster to scare you, but not to kill you. They designed it to give you the experience of chaos, but it’s a controlled chaos. 

Likewise, when we find ourselves in a roller coaster season of life, when we are faced with situations that seem beyond our control, we can find refuge knowing there’s a sovereign God in heaven who is always in control. 

Because Jesus is Lord, all who love and obey Him can find the calm assurance that He will see them through every season of life. (Luke 8:22-26)
