What is the significance of being united with Christ?

The significance of being united with Christ is multifaceted: it ensures that believers are seen by God as righteous due to Christ's obedience. Romans 5:19 explains that 'just as through the disobedience of the one man the many were made sinners, so also through the obedience of the one man the many will be made righteous.' This union not only delineates believers' identity in Christ but also guarantees their inheritance in the new creation. As part of His body, believers experience divine blessings and assurance of glorification at Christ's return.
