What does the Bible teach about God's chosen people?

According to Hannah's prayer, 'he will keep the feet of his saints' (1 Samuel 2:9), indicating that God has chosen a people for Himself and promises to protect and preserve them. This theme runs throughout Scripture, with clear depictions in the New Testament where believers are described as chosen and sanctified by God's grace. God's people, those set apart to serve Him, are assured of His ongoing presence and guidance in their lives. This assurance allows Christians to face life's uncertainties with hope, knowing that they are cherished, secure, and protected by their Creator.
