How do we know that seeking eternal things is important for Christians?

The importance of seeking eternal things is evident in Paul's concern for the spiritual state of the Philippians. He seeks to send Timothy to comfort them, illustrating how awareness of the church's spiritual health is vital. Paul underscores that true comfort comes from knowing the congregation is rooted in Christ. Thus, seeking the things which are Jesus Christ's fosters not only personal spiritual growth but also the collective health of the church, reinforcing the need for believers to focus on eternal blessings.
