This chapter was interesting primarily because of its resounding simplicity. God's promises to Israel was to establish a mountain (Isa 2) and provide wine (Isa 25:6). With both of these things done in Christ we now worship in the "temple of Jesus" which is the body of Christ. But we also drink from "the vine" which makes us into the body of Christ (1 Cor 10:16-17).
Though simple the encouragement is profound. The promises of Isaiah have come true in Christ and the church. We live as result of the greatest exodus from the greatest exile. And God welcomes us to His mountain with wine.
Joshua Torrey is the sole proprietor of Torrey Gazette (don't tell Alaina) and the fullness of its editorial process. That means everything wrong with TG can legitimately be blamed on him.
