Andrew Bonar emphasizes the profound impact of Onesiphorus on the Apostle Paul, illustrating how this faithful friend provided support and encouragement during Paul's imprisonment. Onesiphorus, whose name means 'one who brings profit,' exemplified true Christian love by visiting Paul in prison, unashamed of his chains, and ministering to him with kindness and practical help. Bonar draws parallels between Onesiphorus and Ebedmelech, highlighting the importance of standing by God's servants in times of trial. He encourages believers to actively support one another, regardless of their gifts, and to live in light of the coming day of Christ's return, where mercy will be fully realized. The sermon concludes with a call to reflect on our own faith and actions in anticipation of that day.
