How do we know that God's love is only found in Christ?

The assertion that God's love is exclusively found in Christ is rooted in the biblical teaching that God's love is a holy and just love. According to 1 John 4:10, the essence of love is not that we loved God, but that He loved us and sent His Son as a propitiation for our sins. This emphasizes that God's love is contingent upon Christ's sacrificial work for His people. God's love cannot extend to the unrepentant sinner without the mediator, Christ, as it would contradict His justice. Therefore, it is only through Christ that we can confidently claim to know and experience God's love.
