As Christians, we need a Christian understanding of suffering. Suffering is not meaningless.
Our Lord Jesus Christ suffered himself. He is the model. He is the one we follow.
Like Jesus, we too will have our passion and death according to the Father’s will for our lives. This is part of being united to Christ. We suffer. We embrace our cross to the end.
We need to be looking to the Lord. We all suffer. We all have to pass from this life to the next. The goal is heaven. There is a purpose to our suffering. The Lord wants us to persevere. Fight the good fight. Keep the faith, and enjoy the eternal prize.
