This, if I am right, is not what we accomplish by disciplining our own selves; this is what God does with us.
YHWH grants both the desire to seek HIM, and the abilities to do all HE tells us to do.
YHWH designed the WAY and PROVIDED SALVATION IN Y'SHUA freely, completely.
We can walk WITH HIM, as Y'SHUA trained the disciples to do DAILY,
or we can reject Y'SHAU, and walk away from HIM as many disciples did in the NT.
