Yes, God's people are kept by His power and will persevere to the end.
The doctrine of the perseverance of the saints affirms that those whom God has saved will continue in faith until the end, supported by divine preservation. 1 Peter 1:5 teaches that we are kept by the power of God through faith unto salvation, emphasizing that our security does not depend on our own efforts but on God's faithfulness. Moreover, Philippians 1:6 assures us that He who began a good work in you will perform it until the day of Jesus Christ, reinforcing the notion that the process of salvation involves both God's initiation and His sustained work in believers' lives. This steadfastness is a source of great comfort and confidence for believers, as they recognize that their perseverance is a manifestation of God's promise to uphold them.
