Paul reminds us that our citizenship is ultimately in heaven. Keeping this in mind moves us beyond optimism or pessimism and into a mindset of hope— that Jesus has already conquered death and whatever is happening here and now, in the end, Jesus triumphs over all.
Based on Philippians 3:17-4:1
Brothers and sisters, join in imitating me, and observe those who live according to the example you have in us. For many live as enemies of the cross of Christ; I have often told you of them, and now I tell you even with tears. Their end is destruction; their god is the belly; and their glory is in their shame; their minds are set on earthly things. But our citizenship is in heaven, and it is from there that we are expecting a Saviour, the Lord Jesus Christ. He will transform the body of our humiliation so that it may be conformed to the body of his glory, by the power that also enables him to make all things subject to himself. Therefore, my brothers and sisters, whom I love and long for, my joy and crown, stand firm in the Lord in this way, my beloved.
