How does faith in Christ change a believer's state?

Upon coming to faith in Christ, believers experience a radical transformation in their state before God. Ephesians 2:1 teaches that individuals are 'dead in trespasses and sins' until they are quickened by the Holy Spirit. This regeneration changes their relationship with God, moving them from condemnation to justification. They are no longer under the law's condemnation, but are freed to live by the Spirit. This change is a vital aspect of the true Christian life, indicating that we live in light of our new identity and calling.
