How do we know God's grace is sufficient for our perseverance?

The Scriptures affirm that we are 'kept by the power of God unto salvation.' This indicates a dynamic interplay between God's sovereign grace and our human responsibility. Philippians 1:6 posits that He who began a good work in us will bring it to completion. However, perseverance requires our active striving, echoing Philippians 2:12 that commands us to work out our salvation with fear and trembling. Our role is not passive; we must engage in prayer, study, and loving obedience to foster spiritual growth. Thus, God's grace is both the foundation and the means by which we continue in faith, while our efforts reflect the covenantal relationship we maintain with Him.
