Biblical scholar N.T. Wright describes the significance of the Book of Acts for the Church:
“Acts begins by saying that in the first book (i.e., the gospel of Luke) the writer described “everything Jesus began to do and teach” (Acts 1:1). The implication is clear. The story of Acts, even after Jesus’s ascension, is about what Jesus continued to do and teach. And the way he did it and taught it was–through his followers.
But of course it doesn’t stop there. When the church does and teaches what Jesus is doing and teaching, it will produce the same reaction that Jesus produced during his public career. A good deal of what the church has to do and say will fly in the face of the “spirit of the age,” what passes for “received wisdom” in this or that generation. So be it. The day the church can no longer say, “We must obey God rather than human beings” (Acts 5:29), it ceases to be the church. This may well mean suffering or persecution. That has been a reality today. Some of the most profound passages in the New Testament are those in which the church’s own sufferings are related directly to those of Jesus, its Messiah and Lord. Kingdom and cross went together in his own work; they will go together in the kingdom work of his followers. (Simply Jesus, p. 220)
We Christians not only live in and for Christ, we suffer with Him – in fact, we die and rise with Him.
Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? We were buried therefore with him by baptism into death, so that as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life. For if we have been united with him in a death like his, we shall certainly be united with him in a resurrection like his. We know that our old self was crucified with him so that the sinful body might be destroyed, and we might no longer be enslaved to sin. For he who has died is freed from sin. But if we have died with Christ, we believe that we shall also live with him. For we know that Christ being raised from the dead will never die again; death no longer has dominion over him. The death he died he died to sin, once for all, but the life he lives he lives to God. So you also must consider yourselves dead to sin and alive to God in Christ Jesus. (Romans 6:3-11)
