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

The immeasurable nature of God's love is articulated in Ephesians 3:18, which speaks of the breadth, length, depth, and height of His love. This language conveys a love that transcends any human experience or measure. Paul emphasizes that true comprehension of this love can only come through faith in Christ. Furthermore, according to Romans 8:38-39, nothing can separate us from this love, reinforcing its vast and unfailing character, which is a cornerstone of our assurance in the Christian faith.
