How does God confirm our faith?

God's confirmation of a believer's faith is evidenced through the work of grace and the testimony of Christ that is established within them. This is highlighted in 1 Corinthians 1:7-8, where it is noted that the testimony of Christ is confirmed in believers, enabling them to lack no gift and remain steadfast until the end. This confirmation is not dependent on human effort but is guaranteed by God's faithfulness and purpose. The assurance of salvation and confirmation of faith come through the knowledge of Christ, ensuring that believers are sustained and strengthened in their walk with Him until they stand blameless before God.
