The Spirit of Sonship: Who Is the Holy Spirit? with Sinclair Ferguson
Summary
The sermon emphasizes the "inward witness" of the Holy Spirit as the strongest proof of Christianity, drawing from John Wesley's father and Paul's writings in Romans 8. This spirit of adoption as sons allows believers to cry "Abba, Father," confirming their identity as children of God. The practical takeaway is to recognize this supreme title of the Spirit as the core of our relationship with God.
