Whether we are blessed or cursed, whether the Lord answers our prayers or withholds His hand is not dependent on our performance. It is not our piety in relative relation to our supplication that determines its approval or rejection. We do not earn blessings anymore than we earn cursing.
It is interesting to note, that it is not our common sins for which we exist in separation from God, but rather in the ethical environment of a broken covenant. As we sin daily, we show ourselves to be sinners, to be covenant breakers; we do what our nature determines we have the freedom to do.
God is not a vending machine into which we insert good works in order to purchase good tidings, or even salvation (Romans 11:35). If we are truly saved from the wrath of God according to His will by His grace (which is the act of saving, not a power to be wielded), why do we persist, then, in the false hope that His hand may be swayed by our will?
Consequently, as much of Christianity insists on pursuing this course, this theology of vision and glory, they will move further from Yahweh, who is only known by the revelation of his speech and acts as found in the holy scriptures and into the embrace of atheism.
