And the glory which You gave Me I have given them, that they may be one just as We are one

John 17:22
And the glory which You gave Me I have given them, that they may be one just as We are one

Personality is a mark of our inner spiritual man. It is that which is exposed outside reflection the person deep inside. When we are at one with God, Jesus is an example of this, our personality would be a reflection of the personality of God. Such a person would think of themselves, not as individuals, but as one in unity with God. This transformation will happen when we surrender to the Holy Spirit and be guided by Him.

Be holy, for I am holy

1 Peter 1:16
.. because it is written, “Be holy, for I am holy.”

God's ultimate desire is to have us be together in oneness with Him. So He had to save us first, so that we can be righteous again and then to make us holy. Being holy is not the condition of joining the heaven club, rather it is a transformation which must take place in every believer. While on earth, there are many interests that will take our attention away and influence us away from holiness. So the first step is to accept that we are supposed to be holy and then to learn not to tolerate anything that influence us into unholiness.
