What does it mean that God will not lose any of His people?

The assurance that God will not lose any of His people is a profound comfort rooted in the sovereignty of God. John 6:39 states, 'This is the Father’s will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day.' This verse emphasizes God's perfect plan for salvation, where each person given to Christ by the Father will ultimately be saved. Thus, it is not the believers who maintain their salvation, but the Lord Himself who sustains them, ensuring their perseverance as part of His divine promise. Therefore, believers can rest in the confidence that their salvation is secure in Christ until the very end.
