The Westminster Shorter Catechism (Q 33) defines justification as “an act of God’ s free grace, wherein he pardons all our sins, and accepts us as righteous in his sight, only for the righteousness of Christ imputed to us, and received by faith alone.” For those who are justified, their sins are no longer held against them—not a single sin they have ever done or will ever do. On the cross, Christ paid the penalty that his people, his saints, deserve for all our sins. God’s wrath, which we deserve, was satisfied by Christ’s sacrifice (Limited/Particular Atonement). Therefore, with the apostle we can rejoice, “He has delivered us from the power of darkness and conveyed us into the kingdom of the Son of His love, in whom we have redemption through His blood, the forgiveness of sins” (Col 1:13-14).
In such security of salvation, may you have a blessed Christmas!
