The Saviour

2 Peter 3:1-4

2 Peter 3:1 This second epistle, beloved, I now write unto you; in both which I stir up your pure minds by way of remembrance: 3:2 That ye may be mindful of the words which were spoken before by the holy prophets, and of the commandment of us the apostles of the Lord and Saviour: 3:3 Knowing this first, that there shall come in the last days scoffers, walking after their own lusts, 3:4 And saying, Where is the promise of his coming? for since the fathers fell asleep, all things continue as they were from the beginning of the creation.
[KJV]

The Saviour here is Jesus (see 2 Peter 2:20).
