Excellent reply and right on point. The parable has to do with the wasting of our talents, failure to plant seeds and the penalty for rejecting God.
As the quoted poster mentioned Jesus used parables as a deflection to protect himself against prosecution before it was His time and still teach...
Interpreting the Bible to anyone's whim is very problematic and leads to really unhealthy practices for instance:
1. Snake handling
2. Denying health benefits to the sick
3. Can lead to defending slavery
All of us need guidence with the scriptures to understand them spiritually correct.
Jehovah witnesses are not Christians:
1. You are correct they do not believe Jesus is the son of God.
2. They do not baptize in the name of the Father, Son and Holy Spirit.
No doubt they have taken Christian elements but the end result is not Christianity.
