Why is being united with Christ important for Christians?

The significance of being united with Christ lies in the security and identity it provides for believers. This union means that all distinctions are removed—there is neither Jew nor Greek, bond nor free, male nor female; all are one in Christ Jesus (Galatians 3:28). This profound truth emphasizes the collective identity of believers who share in Christ's righteousness and inheritance, whereby they are considered heirs according to the promise. The implication is that Christians can find comfort and assurance in their standing before God, knowing that they are accepted not on their own merit but through their vital connection with Christ, the beloved Son of God.
