How do we know God justifies us?

The assurance of our justification comes from God's promise as declared in Scripture. Romans 8:33 asserts that 'It is God that justifies,' which guarantees that our acceptance before God rests entirely on His grace and mercy. Moreover, the believer experiences the internal witness of the Holy Spirit, affirming that they are no longer under condemnation but are a new creation in Christ. This act of justification brings about true transformation, security, and liberty, allowing us to approach God with confidence and joy.
