In this sermon, the preacher focuses on the concept of law and grace in the book of Galatians. He explains that before the coming of Jesus, humanity was bound by the Old Testament law, which brought them into bondage rather than setting them free. However, when the fullness of time came, God sent His Son to redeem those under the law and offer them adoption as sons. Through this redemption, believers receive the Spirit of God, who dwells in their hearts and enables them to cry out to God as their Father. The preacher emphasizes the significance of this revelation and encourages listeners to appreciate the indwelling presence of God and the law written in their hearts.

Harmon A. Baldwin addresses the dangerous doctrine of 'suppression' which teaches that depravity always lurks beneath consciousness, advocating for the eradication of the carnal nature from the soul. He contrasts this with the biblical teaching of sanctification and cleansing through Christ's sacrifice, emphasizing the possibility of living a holy and blameless life. Baldwin challenges the idea that the baptism of the Holy Spirit does not involve cleansing from sin, urging believers to allow the Spirit to rid them of the old man instead of suppressing him.

A.B. Simpson explores the life of Isaac, emphasizing how his birth symbolizes the new birth through the Spirit and the promise of God. He contrasts Isaac with Ishmael, representing the law and flesh, and discusses the expulsion of Ishmael as a metaphor for the Christian's struggle against sin. Simpson highlights the significance of Isaac's willingness to be sacrificed, paralleling it with the surrender of self to God, and concludes with the importance of living in the Spirit and the blessings that come from obedience to God's covenant. The sermon encourages believers to embrace their identity in Christ and the transformative power of grace.

Michael Durham preaches on the importance of living in the spiritual realm while navigating the material realm, emphasizing the need to operate by faith rather than sight. He uses the story of Abraham, Ishmael, and Isaac to illustrate the struggle between the natural and spiritual realms, highlighting the necessity of letting go of our 'Ishmaels' - things we hold onto in the natural realm that hinder God's supernatural work in our lives. Durham explains how big mistakes often follow big spiritual moments due to pride and the misconception of God's favor, urging believers to trust in God's supernatural activity and release control to Him.
