Answer: Justification means our declared righteousness before God, made possible by Christ’s death and resurrection for us. Sanctification means our gradual, growing righteousness, made possible by the Spirit’s work in us.
Scripture: 1 Peter 1:1-2 – Peter, an apostle of Jesus Christ, To those who are elect exiles of the dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia, according to the foreknowledge of God the Father, in the sanctification of the Spirit, for obedience to Jesus Christ and for sprinkling with his blood: May grace and peace be multiplied to you.
