“Heaven is the place and sphere from where the universe is sustained and ruled. Heaven is the place and sphere from where salvation goes forth into the world of space and time.
For God’s salvation to be a universal and everlasting salvation, the incarnate Son, Jesus the Messiah, returned to heaven where He could be the source of salvation everywhere to all who believe.
From heaven, through the agency of the Holy Spirit the incarnate Son preaches the Word of God, builds up God’s church, and continues the divine work that began in the restricted area of Palestine.”
–Peter Toon, The Ascension of Our LORD (Nashville: Nelson, 1984), xiii.
“Spirit-inspired preaching about Jesus is the way in which His power and authority are made known and people are enabled to respond to the great saving events of His death, resurrection and ascension. In this way they may engage with the ascended Lord Himself…
In the perspective of Acts, the glorified Lord Jesus is the new point of contact between heaven and earth for people of every race without distinction. The focus is not so much on His redemptive work as a fulfillment of the sacrificial system, but on the idea that God’s glory and kingly power are supremely expressed in Christ…
Preaching about Christ must be at the heart of a Christian theology of worship. As in the Old Testament, the word of the Lord is central to a genuine encounter with God. Those who are concerned about God-honouring worship will be concerned about the proclamation of the gospel, in the world and in the church, in public teaching and private dialogue.
If worship is an engagement with God on the terms that He proposes and in the way that He alone makes possible, preaching Christ is a key to that engagement. Acts points to the proclamation of the heavenly rule of Christ, with all its implications, as the means chosen by God to draw people into relationship with Himself, through Christ, in the power of the Holy Spirit.
God’s great act of redemption in Christ is the basis of a call to enter into and enjoy the blessings of the new covenant. Worship in New Testament terms means responding with one’s whole life and being to the divine kingship of Jesus.”
–David Peterson, Engaging With God: A Biblical Theology of Worship (Downers Grove: InterVarsity Press, 1992), 143-144.
49. Q. How does Christ’s ascension into heaven benefit us?
A. First, He is our Advocate in heaven before His Father. Second, we have our flesh in heaven as a sure pledge that He, our Head, will also take us, His members, up to Himself. Third, He sends us His Spirit as a further guarantee, by whose power we seek the things that are above, where Christ is, seated at the right hand of God, and not the things that are on earth.
