How do we know that Christians are God's chosen people?

The assurance that Christians are God's chosen people is grounded in Scripture, particularly in passages like Malachi 3:17, which states, 'They shall be mine, saith the Lord of hosts.' This divine promise indicates that those who fear the Lord and think upon His name are precious to God. The assurance of being chosen is reinforced by the presence of the Holy Spirit in their lives, leading them to love God and seek a relationship with Him. Furthermore, Christians' transformation and choices reflect this divine election, as they live out their faith, demonstrating that they belong to God.
