Baptism: a Seal of Ingrafting into Christ [2026.05.10 Sabbath School lesson in WCF 28.1.d—Theology Simply Explained]

Baptism is a sacrament of the New Testament, ordained by Jesus Christ,(a) not only for the solemn admission of the party baptized into the visible Church,(b) but also to be unto him a sign and seal of the covenant of grace,(c) of his ingrafting into Christ,(d) of regeneration,(e) of remission of sins,(f) and of his giving up unto God, through Jesus Christ, to walk in newness of life:(g) which sacrament is, by Christ’s own appointment, to be continued in his Church until the end of the world.(h) (click here to DOWNLOAD mp3/pdf files of this lesson) Summary of the transcript of the audio: The lesson centers on baptism as a sacred sign and seal of union with Christ, emphasizing that true faith involves being spiritually engrafted into Christ, the true vine, where believers are no longer dead in sin but alive in Him. Drawing from Romans 6:3–5 and Galatians 3:27, it explains that baptism symbolizes not merely ritual washing but a profound spiritual reality: dying to sin and rising to new life in Christ, a union that secures all of Christ’s benefits and demands total allegiance. The preacher underscores that this union is not partial or conditional but comprehensive—believers receive the whole Christ, and Christ receives the whole believer, making continued sin incompatible with genuine faith. Through pastoral insight and biblical exegesis, the message confronts the dangerous logic of using grace as license for sin, instead calling for a life of obedience and sanctification rooted in the believer’s identity in Christ. Ultimately, baptism serves as a divine guarantee and a continual call to live as one who has been united to Christ, walking in newness of life and resting wholly in Him.

Rooted in Christ’s authority , it signifies and seals the believer’s union with Christ in His death, burial, and resurrection, thereby guaranteeing the spiritual realities of regeneration, remission of sins, and newness of life. Baptism is a sovereign act of God, administered by Christ through His church, and it establishes the believer’s identity as a member of the one body of Christ, regardless of personal feelings or perceived spiritual inadequacy. The sacrament calls for a faithful response of repentance, faith, and obedience, reminding believers that their salvation is not self-achieved but sustained by Christ’s power and promise. As such, baptism is not only a past event but a living reality that shapes the Christian’s ongoing walk in holiness and dependence on Christ.

Sacraments, New and Old [2026.04.26 Sabbath School lesson in WCF 27.4–5 — Hopewell 101]

There be only two sacraments ordained by Christ our Lord in the Gospel, that is to say, Baptism and the Supper of the Lord: neither of which may be dispensed by any but by a minister of the Word lawfully ordained. The sacraments of the old testament, in regard of the spiritual things thereby signified and exhibited, were, for substance, the same with those of the new.

How Sacraments Work [2026.04.19 Sabbath School lesson in WCF 27.3—Hopewell 101]

WCF 27.3 The grace which is exhibited in or by the sacraments rightly used, is not conferred by any power in them; neither doth the efficacy of a sacrament depend upon the piety or intention of him that doth administer it: but upon the work of the Spirit, and the word of institution, which contains, together with a precept authorizing the use thereof, a promise of benefit to worthy receivers.

(click here to DOWNLOAD mp3/pdf files of this lesson) Summary of the transcript of the audio: The lesson establishes that sacraments—baptism and the Lord's Supper—are divine signs and seals of the covenant of grace, instituted by God to visibly distinguish His church from the world, and call them to live in the world as His own. The sacraments are not magical rituals but means through which God strengthens faith, reminds believers of their union with Christ, and challenges them to live in accordance with their identity in Him. Ultimately, they serve both to identify the church and to engage its members in faithful obedience to Christ according to His Word.

Signs That Point Us to Christ [2026.03.08 Sabbath School in WCF 27.1.3—Hopewell 101]

WCF 27.1.3 teaches us that the sacraments point us to Christ. The lesson centers on the sacraments as holy signs and seals of the covenant of grace, emphasizing their role in representing Christ and confirming each believer’s personal, particular interest in Him. Drawing from 1 Corinthians 10–11, it warns against misusing the visible church and sacramental signs—such as baptism and the Lord’s Supper—as mere external privileges, reminding the congregation that spiritual participation requires faith and obedience. Pastor underscores that the Israelites’ experiences in the wilderness serve as cautionary examples: unbelief and presumption led to judgment, illustrating that sacraments do not guarantee salvation apart from genuine faith in Christ. Believers must examine their hearts, avoid the error of thinking they can live freely in sin under grace, and instead look to God to use the sacraments to deepen their assurance, grow them in Christlikeness, and make them live in joyful obedience. Ultimately, the sacraments are not about human merit or ritual but about God’s gracious self-communication, confirming that Christ is personally for each believer through the Spirit’s work.(click here to DOWNLOAD an mp3 file of this lesson)

The Covenant and It's Sign [2026.02.22 Sabbath School in WCF 27.1—Hopewell 101]

We learn, from Gen 17, the way that the sign of the covenant relates to the covenant itself. God uses the sign to strengthen our faith, and He honors His sign by taking it seriously. So, we should take the sign seriously, both in being diligent to apply it and meditate upon it, and in taking to heart the hope and comfort of it. (click here to DOWNLOAD mp3/pdf files of this lesson) Summary of the transcript of the audio: The lesson centers on the theological significance of signs and seals—particularly circumcision in Abraham’s life and baptism in the lives of believers—as divine means of strengthening faith and reinforcing God’s covenant promises. Drawing from Romans 4 and Genesis 17, it emphasizes that these sacraments are not magical rituals but meaningful signs and seals that reinforce faith in God’s power to give life to the dead and call into existence what does not yet exist. The narrative traces Abraham’s journey from unbelief, marked by the birth of Ishmael through human effort, to renewed faith at age 99, when God reaffirms His covenant and institutes circumcision as a sign and seal of the faith already credited to Abraham. The lesson warns against both the superstitious use of the sacraments and the neglect of their spiritual significance, affirming that their true power lies not in the ritual but in God Himself, Who uses them. It applies this truth to Christian parenting, highlighting how baptism serves as a seal of God’s promise to save children by the same grace, through the same faith, that saved their parents.
