Excellent points everyone!
The Watchtower does a wonderful job in taking scriptures out of context and then stringing them together to make it fit their preconceived ideas and there agenda. They are very elitist when they try to elevate on group above another. One group gets immortal life in heaven while the other has to slave away over and over the PROVE and work for their salvation only to MAYBE get life on earth. What did Jesus die for then?
The "other sheep" is not some class that is different in DESTINATION - they are the gentiles who by means of the New Covenant and Jesus' shed blood can now become part of the Kingdom. They are other sheep because they were NOT part of God's original chosen nation. These TWO groups will become ONE flock under ONE shepard. They have the same DESTINATION. It's all revealed in the scriptures when it discusses the sacred secret. It's all there in plain writing. Although to see it you must remove your tainted Watchtower glasses.
