“Their leader will be one of their own; their ruler will arise from among them. I will bring him near and he will come close to me— for who is he who will devote himself to be close to me?’ declares the Lord.”
“Their prince shall be one of their own, their ruler shall come from their midst; I will bring him near, and he shall approach me, for who would otherwise dare to approach me? says the Lord.”
The first translation of Jeremiah 30 : 21 from the NIV is more literal (see older translations), but the second, the NRSV rendering followed by English translations I checked probably brings out the sense better as an NET footnote suggests. The idea from scripture is that God makes a way in this case for a ruler over his people to approach him, even to draw near into his presence. In and through Jesus we know that God has opened the way into the Most Holy by no less than the blood of Christ (book of Hebrews).
This is in large part what good liturgy reflecting scripture helps worshippers do. God in scripture is holy, *other* than humans, so that he is unapproachable. That may be in terms of our own inability, not to mention unwillingness to do so. There is also no doubt in scripture that God himself is a God of judgment who even displays wrath against sin and wickedness. But who also in love makes a way to come near to him, sinners though we are, through the blood of Christ, through Christ’s once for all sacrifice on the cross for sin.
I probably would prefer something more like the NRSV rendering here, but perhaps bringing out something of both renderings. This is to be what we in Jesus are practicing in our worship gatherings and from day to day. A priority of life for us in and through Jesus.
