God our Savior: kindness and love (3:4), mercy (3:5), poured out—God’s generosity (3:6).
“The Lord, the Lord God, compassionate and gracious, slow to anger, and abounding in lovingkindness and truth; who keeps lovingkindness for thousands, who forgives iniquity, transgression and sin” (Exodus 34:6,7).
The blessings of salvation:
Washing of regeneration and renewal through the Holy Spirit (3:5,6). Clean means pure, no longer defiled (see 1 Corinthians 6:11). Regeneration means to be made new. The gospel doesn’t call us to a better life, but a new life, a new creation (2 Corinthians 5:17). Remember that Jesus told Nicodemus, “You must be born again” (John 3:3,7). Renewal by the Holy Spirit relates to the transformation brought on by the new creation we have become in Christ.
Justification (3:7). Justified means being made wholly acceptable, without defect. This comes to us by God’s grace, as a gift, not by works (Galatians 2:16; 1 Corinthians 6:11; Romans 3:24). Being justified, we share in Christ’s righteousness (2 Corinthians 5:21). This is more than being forgiven; it is the moral perfection of Christ given to us as a new creation. One day, freed from this broken world, we will fully see our Christlikeness: “Beloved, now we are children of God, and it has not appeared as yet what we will be. We know that when he appears, we will be like him, because we will see him just as he is” (1 John 3:2).
Heirs (3:8). The gospel blesses us with inclusion into God’s family (John 1:12). “[Our adoption as God’s children] is the highest privilege that the gospel offers: higher even than justification… Adoption is a family idea, conceived in terms of love, and viewing God as father. In adoption, God takes us into his family and fellowship—he establishes us as his children and heirs.” —J.I. Packer, Knowing God
