How do we know Jesus is our beloved?

In the context of the Song of Solomon, Christ is described as the beloved of His church. The affection and relationship that believers have with Christ is marked by deep intimacy, as illustrated by His purity ('white'), His humanity ('ready'), and His ultimate sacrifice for sin. Believers find in Christ the fulfillment of all their needs and desires, leading to the realization that He is our beloved. This relationship transcends anything else we might hold dear, as His love is eternal and unchanging, providing us with comfort and assurance.
