Adios Moses, Joshua, David, and all the predecessors of Jesus.
Or, we can see that in the OT many believed on a coming Messiah and did their best to live according to the Law with a heart set on honoring God.
The Law won't save them, but their faith will.
Paul contradicts your traditions, yet you persist.
20 Therefore by the deeds of the law no flesh will be justified in His sight, for by the law is the knowledge of sin.
21 But now the righteousness of God apart from the law is revealed, being witnessed by the Law and the Prophets,
22 even the righteousness of God, through faith in Jesus Christ, to all and on all who believe. For there is no difference;
23 for all have sinned and fall short of the glory of God,
24 being justified freely by His grace through the redemption that is in Christ Jesus,
Its clear the OT saints were saved by Grace through Christ. His sacrifice applies to everyone who ever lived:
19 For when Moses had spoken every precept to all the people according to the law, he took the blood of calves and of goats, with water, and scarlet wool, and hyssop, and sprinkled both the book, and all the people,
20 Saying, This is the blood of the testament which God hath enjoined unto you.
21 Moreover he sprinkled with blood both the tabernacle, and all the vessels of the ministry.
22 And almost all things are by the law purged with blood; and without shedding of blood is no remission.
23 It was therefore necessary that the patterns of things in the heavens should be purified with these; but the heavenly things themselves with better sacrifices than these.
24
For Christ is not entered into the holy places made with hands, which are the figures of the true; but into heaven itself, now to appear in the presence of God for us:
25 Nor yet that he should offer himself often, as the high priest entereth into the holy place every year with blood of others;
26 For then must he often have suffered since the foundation of the world: but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself. (Heb. 9:19-26 KJV)
Therefore, Paul says
all Isael shall be saved" in Christ completely contradicting "Adios Moses, Joshua, David, and all the predecessors of Jesus" theory, an odd tradition you obviously invented and are proud of.
And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob: (Rom. 11:26 KJV)
To make your sin even worse, you read and ignored Christ our LORD when He condemned following odd traditions men like you invent, rather than the Word of God:
Thus you nullify the word of God for the sake of your tradition. (Matt. 15:6 NIB)
But that doesn't faze you, not a bit.
Now the only question remaining is:
And why call ye me, Lord, Lord, and do not the things which I say? (Lk. 6:46 KJV)
I hope you choose to repent. Our LORD and Master Jesus Christ is returning soon, and He won't deal lightly with those who don't know Him, and are no profit to Him at all:
24 Then he which had received the one talent came and said, Lord, I knew thee that thou art an hard man, reaping where thou hast not sown, and gathering where thou hast not strawed:
25 And I was afraid, and went and hid thy talent in the earth: lo, there thou hast that is thine.
26 His lord answered and said unto him, Thou wicked and slothful servant, thou knewest that I reap where I sowed not, and gather where I have not strawed:
27 Thou oughtest therefore to have put my money to the exchangers, and then at my coming I should have received mine own with usury.
28 Take therefore the talent from him, and give it unto him which hath ten talents.
29 For unto every one that hath shall be given, and he shall have abundance: but from him that hath not shall be taken away even that which he hath.
30 And cast ye the unprofitable servant into outer darkness: there shall be weeping and gnashing of teeth.
(Matt. 25:24-30 KJV)
11 And when the king came in to see the guests, he saw there a man which had not on a wedding garment:
12 And he saith unto him, Friend, how camest thou in hither not having a wedding garment? And he was speechless.
13 Then said the king to the servants, Bind him hand and foot, and take him away, and cast him into outer darkness; there shall be weeping and gnashing of teeth.
14 For many are called, but few are chosen. (Matt. 22:11-14 KJV)
