How do we know that all believers stand equally before God?

In the theology of sovereign grace, it is essential to understand that all believers, regardless of their maturity or years of faith, share a common standing before God. This is reflected in the writings of Paul, where he emphasizes that believers are justified by faith in Jesus Christ alone (Romans 5:1-2). As 1 John 2 reiterates, regardless of one's stage in spiritual growth, all have received forgiveness for His namesake, which signifies that their standing does not change over time. The doctrine of justification tells us that all believers, whether new or seasoned, have the same basis for acceptance before God, rooted entirely in Christ's atoning work.
