To disbelieve is NOT to know it as true and disagree with it.
To disbelieve is NOT to know something as true and refuse to submit to it.
To disbelieve is to not think it true at all.
To disbelieve is to disregard it as true because you think parts of it are false.
To disbelieve is to disregard something as true because you have distorted that something.
So if a person disbelieves the Gospel it is because they do not see it as true.
They disbelieve the Gospel by distorting it,
They disbelieve the Gospel by rejecting part of it as true.
They disbelieve the Gospel and do not know the veracity of it.
And since they disbelieve the Gospel, they can not from the heart trust in its message or in its object, Jesus.
They can not will themselves to believe from the heart what they do not see as true.
The disbelieving Jews of the NT days could not will themselves to believe that Jesus was their Messiah.
It was not a moral choice.
It is still not a moral choice.
A moral choice is a choice to obey or to sin. If you don’t obey, you sin. It is always governed by the Law of God. If you go against His law, you sin. If you don’t sin, it is because you obeyed His Law.
To believe is not a moral choice. It is not an obedience to Law, To disbelieve is not a sin.
Galatians 3 tells us:
Now that no one is justified by the Law before God is evident; for, “The righteous man shall live by faith.” However, the Law is not of faith; on the contrary, “He who practices them shall live by them.”
And those who fail to practice them -to obey- shall die by his deeds. That is Law.
But the righteous shall live by faith.
The Law demands moral excellence. Jesus fulfilled the Law and thereby did not earn death. We all fail to fulfill the Law and thereby earn death. To say that the Law demands moral excellence means that it demands 100% every time all the time obedience. We have all missed the mark. We all have sinned.
But thankfully we do not gain heaven because of our moral choice record, We can be declared righteous -justified- by faith. If we believe we are justified. It is not just another moral choice. It is not a moral choice at all. Because the law is not of faith and likewise, faith is not of the Law.
For by grace you have been saved through faith; and that not of yourselves, it is the gift of God;
If to believe is not a moral choice is it a choice? No.
One can not by the will make the heart know the truth of the Gospel. You hear it and either believe it or disbelieve it. Either you know it is true [from the heart] or you reject it as true. Some might be confused on it for a while, but eventually the disposition of the heart towards the Gospel will win the day.
To believe the Gospel means it has seized your heart with its truth. It means that Jesus has revealed Himself to you, the glory of God in the cross of Calvary.
To believe the Gospel means that you have experienced Christ.
To believe the Gospel means you desire Jesus as Lord.
To believe the Gospel means you are humbled by the hand of God and are grateful.
To believe the Gospel means your sins are forgiven, and yes even, you stand before God clean -justified, even righteous.
To believe the Gospel means you have been born again -of God.
To believe the Gospel -nowadays- means you are filled with the Holy Spirit.
To believe the Gospel means you are united with Christ. You are part of His Body, the Church, the family of God, now and forever.
To believe the Gospel means you will always believe it since believing it never depended on your fickle will, your weak character, or your raised-in-this-world mind.
To believe the Gospel means God, and God alone has saved you.
Give Him all the glory.
