If we don't remember that, we won't be ready when it comes. The temptation will be to avoid suffering at all costs. To pursue happiness in this life at the expense of our faith in Christ. Today's passage is not about happiness. But it does reveal the secret of something far deeper - the joy that comes from the sure hope of eternal life in Christ.
Christians are a praising people.
Full of joy and the Holy Spirit. Think about it. Death is not the end. You won' t have to face judgement for your sins. Christ has done it for you.
