As Jesus said:
Amen.
It was only when I understood that I had NOTHING to do with hearing Christ that I actually began to hear Him clearly for the first time in Scripture.
We know that we must be born again in order to understand the things of God, and John tells us we are "born, not of blood, nor of the will of the flesh, nor of the will of man, but of God."
The funny thing is that as you come to realize all good things in you are the work of the Holy Spirit and not your own, you actually want to try harder.
And even that is the work of God in you.
It all comes back to the source.
