The Bible is full of people who experienced seasonal changes in their life, but their faith didn't waver. Despite the fact that Joseph was thrown in prison for 13 years for a crime he didn't commit, God never forgot about him. Job lost everything but God remained faithful. Stephen was stoned to death, but Jesus showed him His glory. Seasons will change in our life, however we must not forget that Jesus is the constant who remains the same forever and ever and there is no greater foundation than Him.
