'If in fact in 1919 the faithful slave was chosen as God’s channel on earth, and Christ Jesus, the Master approved of them, why is it that we do not still teach the things taught back then? Why are they considered, "old light"? Yet it was considered truth for that time. Truth does not revert back to falsehood if it was indeed truth to begin with. Why has the slave rejected what the master had approved of?"
The truth never EVER changes but the understanding of that truth has and will continue right to the END,
its like the bright morning light that grows brighter and brighter.
Proverbs 4:18 NWT
But the path of the righteous is like the bright morning light
That grows brighter and brighter until full daylight.+
I addressed this before as to why the understanding has evolved over the years,
does the passage say :
the path of the righteous is like the a bright morning light,that's its brightest in the morning as well as daylight?
NO,its gradual progression ,brighter and brighter suggest learning and understanding in stages not full knowledge from the beginning,How can it be expected Zions Watchtower
have complete understanding of Gods will when the apostles who were with Jesus didnt completely understand his teachings even after he died and was resurrected?
Example:
Jesus said over and over his Kingdom was New Jerusalem in heaven not the earthy city in Israel,in fact he predicted the temple would be destroyed as proof.
New Living Translation John 18:36
Jesus
answered, “My Kingdom is not an earthly kingdom. If it were, my
followers would fight to keep me from being handed over to the Jewish
leaders. But my Kingdom is not of this world.”
Yet his followers asked this question after Jesus was resurrected
Acts 1-6 NIV
Then they gathered around him and asked him, “Lord, are you at this time going to restore the kingdom to Israel?”
Why would they ask this question about an earthly Kingdom over in Israel in view of his constant teaching about his heavenly New Jerusalem?
Because they didnt understand fully about New Jerusalem and they wanted relief right then from Roman rule,they had no idea Jesus was leaving soon to set up his heavenly Kingdom.
There are other instances when they didnt fully understand his teaching and would privately ask Jesus what he meant .
So the Slave in 1919 after leaving false religious teachings of Satan should have understood Jehovah's truths from the very beginning when Jesus followers who were right there with the great teacher didnt fully understand some of his basic teachings
