There's lots about both. The elect ARE His sheep. In addition,:
34 Then the king will say to those on his right, Come, you who are blessed by my Father. Inherit the kingdom prepared for you from the foundation of the world.
Who else could possibly be referred to except the elect? He's talking to the sheep.
Amen!
And all mine are thine, and thine are mine; and I am glorified in them." -- John 17:9-10"I pray for them: I pray not for the world, but for them which thou hast given me; for they are thine.
Bahhh.
The identification of the sheep and the goats is as clear as a sunny day in the Arctic. The sheep are those who have done His will and the goats are those who have not.
If you say that only those who have done His will are the elect, then perhaps we can take this discussion a little further on what constitutes the elect and who on Earth can do His will. And who cannot.
