I have spoken to you of earthly things and you do not believe; how then will you believe if I speak of heavenly things?
The Messiah spoke about issues like paying taxes, and forgiving or neighbor. This was in regards to Earthly things, issues we can feel, smell or see with our own eyes. But sine the teachers of the Torah were not willing to obey Jesus in such issues, why would they listen to the explanation about the Kingdom of Heaven? This is a place in the Spiritual realm, something we can not see or touch. But is there. Listen to Jesus, before its to late.
