Gen. 26:4 And I will make thy seed to multiply as the stars of heaven, and will give unto thy seed all these countries; and in thy seed shall all the nations of the earth be blessed;
5 Because that Abraham obeyed my voice, and kept my charge, my commandments, my statutes, and my laws.
I might humbly suggest we all have works. To say otherwise seems foolish. Passover (Grace) has spiritually happened before the foundation of the world.
Rev. 13:
8 And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world.
This "Grace" has come to all men no matter who they are or what they have done. Mankind's action had nothing to do with God's Grace.
This was part of God's plan from the very beginning.
Gen. 1:
1 In the beginning God created the heaven and the earth.
2 And the earth was without form, and void; and darkness
was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
3 And God said, Let there be light: and there was light.
4 And God saw the light,
that it was good:
and God divided the light from the darkness.
Rom. 3:
23 For all have sinned, and come short of the glory of God;
24 Being justified freely by his grace through the redemption that is in Christ Jesus:
25 Whom God hath set forth
to be a propitiation through faith in his blood,
to declare his righteousness for the remission of sins that are past, through the forbearance of God;
There was an Old Covenant that fore shadowed this truth called the "Levitical Priesthood". It was comprised of several ceremonies and sacrificial "deeds or works" performed by the Levite Priest's for the remission and justification of sins. Jesus is now our High Priest and has "fulfilled" these "works of the Law" for remission of sins.
Paul is speaking to this in:
Romans 3.
1 What advantage then hath the Jew? or what profit
is there of circumcision?
2 Much every way: chiefly, because that unto them were committed the oracles of God. (Which also included the Levitical Priesthood "Works of the Law" for remission of sins.)
But now we have Christ's Blood once and for all. No more need of the "Old Covenant" for remission of sins, we now have faith(obedience).
Rom. 3:
20 Therefore by the
deeds of the law (Levitical Priesthood ceremonies and sacrificial observances) there shall no flesh be justified in his sight:
for by the law is the knowledge of sin.
The law shows us the definition of sin, it can't forgive us of our sin.
Passover (Grace) is not the end of God's Salvation for mankind, it is the beginning.
This is why Jesus said to "Seek ye FIRST the Kingdom of God and His Righteousness". And what do we do when we find HIS RIGHTEOUSNESS? Well I would say ignoring it is not the right answer. Paul explained what happened to the Mainstream, God of Abraham preaching" Church of his time.
Rom. 10:
2 For I bear them record that they have a zeal of God, but not according to knowledge.
3 For they being ignorant of God's righteousness,
and going about to establish their own righteousness,
have not submitted themselves unto the righteousness of God.
Everyone has works. The question is, are they from God or man?
