In this life is joy and sorrow, elation and suffering. All of us go through the ups and downs of life. At times our choices and decisions bring sorrow and suffering upon us. Suffering can take the form of caring for a family member dying from an illness. Suffering can come in how people treat us because of our faith. Suffering can come from the decision we make based upon our faith in Jesus Christ. All of these things are part of the cost of following. All of these things also test us. Despite the testing being difficult, it will help us grow in our faith.
Peter tells us that we should rejoice in our suffering for Christ because that will bring us a greater joy when His glory is revealed. By accepting and embracing the sufferings, we can draw closer to Christ, the source of our strength. In times when we rely on Him, we become less and He becomes more. In this we begin to see His glory revealed. It is only a glimpse now, but we begin to see what it may be. And, in the end, He will make our joy complete.
