Last Judgement — Final Transition.
In British courts of law the route to becoming a judge is to serve first as an advocate (quaintly called a barrister in England) and we find the same progression in heavenly courts leading up to the Last Judgement itself:
My little children, I am writing these things to you so that you may not sin. But if anyone does sin, we have an advocate with the Father, Jesus Christ the righteous. [1 John 2:1]Now is the time to make use of his advocacy and the access we have through him to the Father.
