A biblical exploration of how we should worship. Sproul shows how to follow the principles and models in Scripture. He points out that we must ensure that all we do in worship is to God's glory and honor, and according to His will. We must worship God as He has decreed, so we're not free to simply worship as we desire.
Sproul asks the thought-provoking questions, "What is pleasing to God? If God were to design worship, what would it look like?" He points out that vast portions of the Old Testament specifically tell us God's ordained style and practice of worship for His OT people. Because God is more explicit in the OT than the NT about how He wishes to be worshipped, Sproul draws principles from there. He does explain several times that we can't simply carry OT style and practice into the NT, because the OT sacrificial system was fulfilled by Christ. Although there is discontinuity between OT and NT, there is continuity in that God has not changed.
Sproul also explains how the senses should be engaged in worship.
Items Sproul doesn't discuss (as far as I recall): who can lead in worship, giving offerings in worship, the day of worship, or the number of worship services on that day.
Notes
Sacrifices in Faith
Problem with Cain's offering wasn't what he offered, but how he offered it (without faith or reverence). Heb 11:4.
The House of Prayer
While Zacharias prayed, congregation also prayed. No reason this wouldn't continue to NT church. Congregation should participate with pastor in directed, corporate prayer: pastor directs congregation to pray by name for those who are ill, burdened, mourning, and congregants say aloud names of people about whom they're concerned.
Symbolism in Worship
Christ ordained and consecrated bread and wine for communion, not other food and drink. We should use bread and wine to worship God as He directs. Alternatives may be acceptable in extreme circumstances (such as a concentration camp).
Baptism: Part 2
NT baptism was instituted by Jesus in Matt 28:19, which was different than baptism of John the Baptist (sign of repentance given to Jews in preparation for Messiah, not covenantal sign).
Baptism is an outward sign of promise of God. When Christian comes to faith, that shows God has kept His promise. God hasn't failed to keep His promise, so no need to be baptized again.
To You And Your Children
NT doesn't command or give clear examples of infant baptism, but doesn't explicitly forbid either, or teach that profession of faith is required before baptism.
OT sign of faith and covenant, circumcision, was given to infants. NT sign of faith and covenant, baptism, should be too.
NT command to "repent and be baptized" or "believe and be baptized" is given when audience is adults, not children.
Infants may have been included in one of the 3 household baptisms (Acts 16:15, 33; 1 Cor 1:16). Greek "oikos" translated "household" is at least as weighty as our word "family" which suggests children. In OT, when head of household entered covenant, entire family received benefit. This principle is reaffirmed in NT (1 Cor 7:14).
If God had meant to stop including infants in covenant community in NT, He would've made this plain. 1 Cor assumes continuity of inclusion of infants in covenant. Heb says new covenant is more inclusive than old.
Infant baptisms aren't mentioned until middle of 2nd century, but they're spoken of as universal practice of church. There's no record of this practice changing after apostles.
Lord's Supper
Christ is really present at Lord's Supper, but His presence isn't tied to bread and wine, and He's not physically present.
Only Jesus' divine nature is omnipresent (Matt 28:20); His human nature isn't (John 7:33), and thus can't be present at Lord's Supper celebrated around globe.
In Lord's Supper, we are communing with whole Christ, because we commune with united person of Christ (human and divine).
The Whole Person
God's people must worship Him in truth (John 4:24). Mind must be actively engaged in worship. Reading and preaching of Bible are important, because they lead to understanding.
In addition to involving mind, OT worship involved 5 senses.
The Sounds of Worship
Ps 150:3-5 says to praise God with trumpet, lute, harp, timbrel, stringed instruments, flutes, cymbals. Nothing written later removes legitimacy of praising with these instruments.
We don't need to limit singing to Psalms, but whatever we sing must be theologically and biblically sound.
The Touch of Eternity
Jesus used wine in Lord's Supper. By its taste, wine communicates pain and joy, sorrow and gladness of Christ's death; grape juice doesn't.
