The phrase "How deep the Father's love for us" expresses a profound and immeasurable love that a Father has, especially referring to God's love for humanity. It is often described as vast beyond all measure, sacrificial, and unconditional, such that the Father gave His only Son to save and redeem people, exemplifying a love that is selfless and enduring despite human flaws or failures. This love is depicted as deeply personal, compassionate, and constant, not based on human merit but on relationship and grace. This concept is notably conveyed in the Christian hymn "How Deep the Father's Love for Us" by Stuart Townend, which highlights the depth of God's sacrificial love as demonstrated through Jesus Christ's suffering and death on the cross. The hymn reflects on the pain of loss the Father endured, the sin borne by Christ, and the redemption offered freely out of this immense love. The love is "vast beyond all measure" and "how great the pain of searing loss" but remains transformative, bringing "many sons to glory" and offering life and ransom to those loved.

Additionally, an earthly father's love for his children is described as instant, unconditional, and ingrained—one that seeks relationship and never gives up on the child regardless of challenges or separation. The father's love is pictured as hopeful and compassionate, always longing to reconcile and embrace the child, reflecting a deep and persistent care.

In summary, the depth of a father's love, both human and divine, is boundless, sacrificial, and unwavering—marked by commitment, grace, and compassion beyond measure. This captures both spiritual and earthly dimensions of the phrase "How deep the Father's love for us."
