Justification is something that happens externally from us. It is accomplished by the sinless life, substitutionary death, and bodily resurrection of Jesus Christ in our place, for our sins, as our savior. It is a legal transaction in the sight of God for those whose faith is in Christ. Practically, this means your righteous in Christ. God can’t love you anymore, and he will never love you any less. You do not have to be perfect, because Jesus is. You don’t have to pay God back, because Jesus ask. You don’t need to suffer for your sense, because Jesus did. You are free to stop working for your righteousness and start working from Jesus’s righteousness.
