How do we know that God's love is saving love?

The concept of God's love being saving love is grounded in the biblical assertion that He loves His elect, those whom He has chosen for salvation. In John 11:5, it is noted that 'Jesus loved Martha and her sister and Lazarus.' This love is not a generic love for all humanity but rather a specific, sovereign love that produces saving faith. Furthermore, Romans 9:13 states, 'Jacob have I loved, but Esau have I hated,' indicating that not all are recipients of saving love. This is an essential distinction in understanding how God's love operates in the salvation of individuals.
