So having shown God's sovereignty in the actions of men does not conflict with their free will, the first objection to God's sovereignty is removed, and we can move on to what the Bible presents on the moral responsibility of mankind.
III. Moral Responsibility of Mankind:
The Bible teaches that, even though unregenerate man's will is not free/able to make all moral choices (Jn 8:34) and, therefore, he is unable to choose to obey God (Ro 8:7),
man is still morally responsible/guilty for sin (Ro 3:19b, 14:12).
But how is it just to hold man morally responsible/guilty for sin if he is unable to obey God? An analogy is helpful here.
Suppose an invalid borrowed money from you on the promise that he would repay you from his inheritance at his father's death.
The invalid has contracted a just debt, which he is responsible to pay.
But suppose when the invalid comes into his inheritance, he is conned out of the whole inheritance before his debt is paid.
The invalid is still responsible for his just debt, even though he is unable to pay.
The principle here is that responsibility to pay is not based in ability to pay, but in what is justly owed.
The same is true Biblically.
Responsibility to obey God is not based in man's ability to obey God (which he does not have--Ro 8:7),
but in what man justly owes God.
God is the center of the universe, not man (Rev 4:11).
God is the potter who owns everything he created (Ex 19:5; Dt 10:14; Job 41:11; Ps 24:1, 50:12; Eze 18:4), including man (Is 45:9; Jer 18:6).
He has a right to obedience from man (Lk 17:10) and, therefore, obedience is justly owed to him.
Unregenerate man's spiritual impotency does not release him from that just debt, because man's responsibility does not issue from his ability to pay, but from what he justly owes.
Now, while justice requires the invalid to pay his debt to you, justice will not be done in your case, because the invalid is unable to pay.
However, with God, justice is always done.
If we do not pay our debt (through Jesus Christ), we will be thrown into debtors' prison, even though we are powerless to pay it.
Justice will be exacted of unregenerate man to the last penny (Mt 5:26, 18:34) by God his adversary (Ro 5:10),
with whom he is warned to settle his accounts before they come into God's court of judgment (Mt 5:25).
So unregenerate man is responsible/guilty for his sin of disobedience (Mt 12:36), even though he is unable to obey God (Ro 8:7).
Biblically, inability to obey God does not remove mankind's moral responsibility/guilt for his sin,
and, therefore, there is no injustice in God holding unregenerate mankind accountable for sin (his debt) even though he cannot (pay the debt he justly owes to) obey God.
So of the objections to God's sovereignty in the actions of men, two have now been removed:
1) it is a violation of man's free will, and
2) is is unjust to hold man responsible for what he is unable to do.
to be con't.
