How do we know that God keeps us in our faith?

The assurance of God's faithfulness is found throughout Scripture, particularly in passages like Philippians 1:6, which declares that He who began a good work in us will carry it to completion. This means that our endurance is secured not by our own effort, but by God's promise and power. The faithful witness of the saints who endured before us further emphasizes that true faith is preserved by God. They exemplified a faith that did not fail, showing that those whom God calls will ultimately be kept in their faith and will reach the end of their race.
