The sheep hear his voice; and he calls his own sheep by name

John 10:3
To him the doorkeeper opens, and the sheep hear his voice; and he calls his own sheep by name and leads them out.

There is a special relationship that a shepherd has with his sheep - they know the sound of the shepherd and will respond to him. The analogy of shepherd-sheep is very accurate in many aspects when it comes to describe the relationship between Yshua Lord and His children. It is not just about doctrinal knowledge or believing in the biography of Lord Yshua. It is the oneness with Yshua that we need to come to. There are a few examples of this that we can see from the Scriptures in the people who have developed this oneness with the Lord, such as Mary the sister of Martha, the twelve disciples, Paul the apostle and so on. We need to know the voice of our Lord when he calls.
