No Tanakh,,,they had no idea about the Cross until it happened..Likewise they had no idea (at first) that death was required before one has everlasting life... There will be only a few of the Church who are still living when they are "caught-up", The other members of this Body of Christ will be resurrected from the graves and reconnected to their souls. Yes, Their Eyes, the same ones that they lived with so many years on earth will see Jesus in His Kingdom.... (i.e. Job 19)
as far Back as Isaiah the death and resurrection was preached, Jesus taught His dicsiples thoroughly about His death and resurrection and also his ascention to Gods right Hand. His Death, is Not what stops His words its what Makes them the eternal Authority
the blood of the coveannt is shed after all the coveannt is spoken to the people, Jesus did that, He gave the Gospel and then shed His blood. That Means forever His words are set until the end of the earth. Heres Jesus teaching of His death, and resurrection, His blood shed for sin, His ascention to Gods right Hand...and Paul preaching it
matthew 20:28 " Even as the Son of man came not to be ministered unto, but to minister, and to give his life a ransom for many.
matthew 26:28 " For this is my blood of the new testament, which is shed for many for the remission of sins."
Luke 9:22 " Saying, The Son of man must suffer many things, and be rejected of the elders and chief priests and scribes, and be slain, and be raised the third day."
Luke 22;69 " Hereafter shall the Son of man sit on the right hand of the power of God."
you Know of course that paul also taught the death and resurrection ( its not the cross, its the life death and resurrection and the ascention of Jesus the Christ.romans 8:34 " Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us."
thats why because He went to Gods right hand for a purpose to interceed for us number 1
Number 2 to send the Holy Ghost as He promised in John 14-16.
acts 2 : This Jesus hath God raised up, whereof we all are witnesses. 33Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear.number 3 to enterthe tabernacle in Heaven and serve as Our High priest in the opresence of God in the inner sanctuary and tabernbacle of the testimony. to offer Himself as Our sacrifice ( the Lamb slain)
Hebrews 10:12" But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God;
Hebrews 4 " For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart. 13Neither is there any creature that is not manifest in his sight: but all things are naked and opened unto the eyes of him with whom we have to do.
14Seeing then that we have a great high priest, that is passed into the heavens, Jesus the Son of God, let us hold fast our profession. 15For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin. 16Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need.
Hebrews 7 " By so much was Jesus made a surety of a better testament.23And they truly were many priests, because they were not suffered to continue by reason of death: 24But this man, because he continueth ever, hath an unchangeable priesthood. 25Wherefore he is able also to save them to the uttermost that come unto God by him, seeing he ever liveth to make intercession for them."
