How do we know we are vessels of mercy?

Romans 9:23-24 identifies believers as 'vessels of mercy, which He had afore prepared unto glory.' This assurance is rooted in God's sovereign choice and calling, which is not based on our ethnicity or works but on His divine purpose. The confirmation of being a vessel of mercy comes from experiencing God's grace in our lives and the transformative effects it has, as seen in our faith and steadfastness in trials. Our identity in Christ as vessels of mercy reinforces the hope that we will ultimately partake in the glory He has prepared for us.
