How does Christ's work relate to our status as heirs?

In Galatians 4:4-5, Paul describes how Christ was sent to redeem those under the law so that we might receive adoption as sons. This highlights the essential role of Christ’s sacrificial work in our redemption. His coming, under the law and as a man, was to fulfill the requirements that we could not meet. By His work, we are not only released from the bondage of sin but also elevated to the status of heirs alongside Him, sharing in the riches of grace and promise. Thus, our sonship and inheritance are rooted entirely in Christ's finished work on our behalf.
