How do we know God's love is effectual?

God's love is described in Jeremiah 31:3 as an everlasting love, emphasizing that it is not based on human merit or conditions. The effective nature of God's love means that it achieves its purpose: to draw His chosen people to Himself. As noted in John 6:44, no one comes to Christ unless the Father draws them, illustrating that God's love results in the regeneration and salvation of those He has chosen. Thus, His love is not a mere sentiment; it actively participates in the redemption of His people.
