“Blessed be the God and Father of our Lord Jesus Christ, who according to His great mercy has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead,” – 1 Peter 1:3 (NASB)
Even if we do not know them, there still is one father and one mother for every person created. Though God was known as Creator and Redeemer in the OT, He was rarely called Father except He is in Isaiah and Jeremiah. Jesus Christ, always addressed God as His Father in the gospels except in the separation on the cross (Matthew 27:46). In doing so, Christ claimed to be of the same nature and being, as the Father. Jesus does not forbid the showing of respect when He said “And call no man your father on earth, for you have one Father, who is in heaven.” Christ says no to the use of such names as spiritual titles, or in a sense that accords undue spiritual authority to a human being, as if he were the source of truth rather than God. By speaking of “our” Lord, Peter personalized the Christian’s intimate relationship with the God through His Son. For God provided a glorious salvation for mankind. He is merciful because sinners need God’s mercy. We were in a pitiful, desperate, wretched condition as sinners. Only by God’s mercy are we forgiven and born again.
