John Wesley on Jeremiah 33:16

Saved - It is the opinion of some that a spiritual salvation and security is promised under these expressions, but by the most and best interpreters, a temporal salvation. This was typical of that spiritual and eternal salvation which is promised to the true Israel of God; as their rest in Canaan typified that rest which remaineth for the people of God. The Lord our righteousness - There is no such name any where given, either to the Jewish or Christian church, as the Lord our righteousness, but the full import of that name is spoken of Christ, Isa 45:23, which text is applied to Christ, Rom 14:11 Phil 2:10.
