What does the Bible say about believers being strangers in this world?

In Hebrews 11:13-16, it is explicitly stated that believers in Christ are considered strangers and pilgrims on the earth. They have not yet received the fulfillment of God's promises, yet they are convinced of them and embrace them, demonstrating their longing for a better country that is heavenly. This world is described as a valley of death, affirming that believers walk through it with the assurance of a promised city prepared by God. As they navigate this life, they do so with the understanding that their true home is with God and that their identity is rooted in the eternal promises given to them through Christ.
