Jesus pointed everything to the cross.
John 11:25 KJV Jesus said unto her, I am the resurrection, and the life: he that believeth in me, though he were dead, yet shall he live:
How can he be resurrection and life without death and burial first?
He introduced to them to salvation without works by FAITH.
John 6:28-35 KJV Then said they unto him, What shall we do, that we might work the works of God? (29) Jesus answered and said unto them,
This is the work of God, that ye believe on him whom he hath sent. (30) They said therefore unto him, What sign shewest thou then, that we may see, and believe thee? what dost thou work? (31) Our fathers did eat manna in the desert; as it is written, He gave them bread from heaven to eat. (32) Then Jesus said unto them, Verily, verily, I say unto you, Moses gave you not that bread from heaven; but my Father giveth you the true bread from heaven. (33) For the bread of God is he which cometh down from heaven, and giveth life unto the world. (34) Then said they unto him, Lord, evermore give us this bread. (35) And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst.
He spoke of himself as bread, then led them further and further to the concept of the cross.
John 6:40 KJV And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.
He brought resurrection into the picture again, which the apostles later expounded upon and stated death with Christ leads to that resurrection.
John 6:53 KJV Then Jesus said unto them, Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you.
After having stated the FLESH AND BLOOD give eternal life, they wondered if he meant cannibalism, and He explained that was a PICTURE of HIS WORD.
John 6:63-64 KJV It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life. (64) But there are some of you that believe not. For Jesus knew from the beginning who they were that believed not, and who should betray him.
The flesh he spoke of is not the literal issue, but points to what they must BELIEVE in HIS WORD.
And we see it all come together at the end of His ministry, after having led them up to this through those who 3.5 years.
Matthew 26:26-28 KJV And as they were eating, Jesus took bread, and blessed it, and brake it, and gave it to the disciples, and said, Take, eat; this is my body. (27) And he took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it; (28) For this is my blood of the new testament, which is shed for many for the remission of sins.
The flesh and his blood point to the cross where he would be broken in death and shed blood for remission of sins.
ALL HE SAID pointed to that day of the cross. ALL.
And to stumble over the cross by missing how all he said pointed to it, with GENUINE FAITH and not empty altar activity and lip service that can be done without faith, but is necessarily to follow after GENUINE FAITH, is to be lost as lost can be.
