Who does the Bible say that the "fool" is?
Psa_14:1 To the chief Musician, A Psalm of David. The fool hath said in his heart, There is no God. They are corrupt, they have done abominable works, there is none that doeth good.
Psa_53:1 To the chief Musician upon Mahalath, Maschil, A Psalm of David. The fool hath said in his heart, There is no God. Corrupt are they, and have done abominable iniquity: there is none that doeth good.
They say, "No." to God when God asks them to obey Him in His commandment (Exodus 20:8-11; John 14:15, Exodus 20:6), and thus deny Him.
The Law of Ten Commandments is "good".
Rom_7:12 Wherefore the law is holy, and the commandment holy, and just, and good.
But there are those who say, "Lord, lord" and do not "do" what He commands. As it is said, honoured through lip service alone.
The bible says that the fool is the one who goes back to working at the law after becoming Christian.
Galatians 3:3 Are ye so foolish?
having begun in the Spirit, are ye now made perfect by the flesh?
Why is it foolish to go back to working at the law?
Because the law DOESN'T make anyone righteous. If it did make a person righteous then we would all need to do it.
But there is a problem as well trying to make people go back to their work at the law for "obedience".
Galatians 3:10 For as many as are of the works of the law are under the curse: for it is written, Cursed is every one that continueth not in all things which are written in the book of the law to do them.
See? You can't just decide to work at some of the law and ignore the rest. Cursed is EVERYONE who doesn't continue in ALL THINGS which are written in the book of the law to do them.
Its much better to treat the 10 commandments as the Spiritual Law that they are instead of trying to turn them into a Carnal Law that a person can work at and fulfill in their own strength and understanding.
2 Corinthians 3:7-11
7 But if
the ministration of death, written and engraven in stones, was glorious, so that the children of Israel could not stedfastly behold the face of Moses for the glory of his countenance; which glory was to be done away:
8 How shall not the ministration of the spirit be rather glorious?
9 For if the ministration of condemnation be glory, much more doth the ministration of righteousness exceed in glory.
10 For even that which was made glorious had no glory in this respect, by reason of the glory that excelleth.
11 For if that which is done away was glorious, much more that which remaineth is glorious.
Which one is the Christian under, which one does the Christian obey?
The ministration of death written on stone? Nope. That's for people who have not come to Christ that still have their heart of stone.
The ministration of Righteousness is the One the Christian is under and it is the Ministration of the Spirit that the Christian Obeys.
The carnal understanding and the carnal fulfillment of the law is broken by the Christian (in some cases) but the Real Spiritual intent is kept.
Romans 3:31 Do we then make void the law through faith? God forbid: yea, we establish the law.
