How do we know that God can reconcile us through Christ?

In the sermon, it is highlighted that Paul acts as a mediator between Philemon and Onesimus, reflecting the greater mediation of Christ. Just as Paul pleads for Onesimus, Christ pleads for us before the Father, representing our debt and offering Himself as the payment (Philemon 1:18). This connection illustrates the theological underpinning that reconciles humanity to God through Christ's sacrificial love, confirming that our shortcomings are covered through His grace, so we can be accepted as beloved children of God.
