How do we know we are without sin in God's sight?

The doctrine of imputation teaches that believers in Christ are counted as righteous before God due to the perfect obedience and sacrifice of Jesus. Colossians 1:22 states that Christ presents us 'holy, unblameable, and unreprovable' before God. Our standing before the Father is not based on our works or inherent righteousness, but rather on the perfect righteousness of Christ that is credited to us. This underscores the foundational belief in sovereign grace, where our acceptance is solely dependent on God's grace and Christ's redemptive work.
