How is it that we, who are called by God into His Kingdom, are able to “participate in the divine nature?” Is it due to something inherent in us? Or, is it due to God’s generosity? The answer is obvious — nothing we are, nothing we do explains our “escape [from] the corruption in the world caused by evil desires.” Only the sacrifice of Jesus, the Son of God adequately explains our sharing in the divine being. All other explanations pale by comparison. Avoidance of sin, fervent worship, self-sacrifice, martyrdom — none of these fully meet God’s requirements for being divine.
We are provided with “His divine power [which] gives us everything we need for life and godliness.” (2 Peter 1:3) “[We] are a chosen people, a royal priesthood, a holy nation, a people belonging to God.” (1 Peter 2:9) We are partakers in the divine nature simply because although “once [we] had not received mercy, […] now [we] have received mercy.” (1 Peter 2:10)
God’s mercy is the reason we share in His nature. “In His great mercy, He has given us new birth into a living hope through the resurrection of Jesus Christ from the dead, and into an inheritance that can never perish, spoil or fade — kept in heaven for [us], who through faith are shielded by God’s power.” (1 Peter 1:3-5)
Our faith guarantees our inheritance — not because we generate that faith — but because of the shield of God’s power. God shields us “from the corruption in the world” and seals us for “the coming of the salvation that is ready to be revealed in the last time.” (1 Peter 1:5)
