How do we know that Christ's love is real?

The reality of Christ's love is primarily demonstrated through His sacrificial act of laying down His life for sinners, as mentioned in 1 John 4:10: 'Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins.' Additionally, God's eternal choice of His elect in love, as expressed in 2 Thessalonians 2:13, further affirms that the basis of our salvation is rooted in His everlasting love rather than human merit. This love is not conditional or capricious but is rooted in God's sovereign grace, ensuring that all for whom Christ died will be saved. Thus, the love of God is truly a solid foundation for the believer’s faith.
