Mark 14:17 And in the evening he cometh with the twelve.
Jesus comes to the prepared upper room for his last Passover supper. All twelve were present as he had this final time to speak to them.
Mark 14:18 And as they sat and did eat, Jesus said, Verily I say unto you, One of you which eateth with me shall betray me.
To eat together is one form of fellowship. It is an intimate time together, a special time to get to hear from others and to share personal things.
Rev 3:20 Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me.
Rev 3:21 To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne.
Jesus spoke of one who was at the table who would betray him. He knew peoples hearts and still knows our hearts as well, he is God the Son.
Mark 14:19 And they began to be sorrowful, and to say unto him one by one, Is it I? and another said, Is it I?
Can you imagine Judas pretending not to know? He was perhaps afraid of the others if they should discover that he had made arrangements, for money, to betray the Lord. He feared man, lusted after his own wealth, while denying the Lord that he had been with for three and a half years.
Mark 14:20 And he answered and said unto them, It is one of the twelve, that dippeth with me in the dish.
John's gospel says more of this.
John 13:25 He then lying on Jesus' breast saith unto him, Lord, who is it?
John 13:26 Jesus answered, He it is, to whom I shall give a sop, when I have dipped it. And when he had dipped the sop, he gave it to Judas Iscariot, the son of Simon.
John 13:27 And after the sop Satan entered into him. Then said Jesus unto him, That thou doest, do quickly.
John 13:28 Now no man at the table knew for what intent he spake this unto him.
John 13:29 For some of them thought, because Judas had the bag, that Jesus had said unto him, Buy those things that we have need of against the feast; or, that he should give something to the poor.
John 13:30 He then havingreceived the sop went immediately out: and it was night.
Mark 14:21 The Son of man indeed goeth, as it is written of him: but woe to that man by whom the Son of man is betrayed! good were it for that man if he had never been born.
It is written that he must die and that he would rise again on the third day. But, woe to the one who betrayed him. It would be better that he never was born. It would be better to not be born then to spend eternity in torment in the lake of fire. Do you know that there are many around us who do not have hope or meaning in their lives? They need Jesus.
Judas would seek to repent, but he went the wrong people, those who wanted Jesus dead.
Mat 27:3 Then Judas, which had betrayed him, when he saw that he was condemned, repented himself, and brought again the thirty pieces of silver to the chief priests and elders,
Mat 27:4 Saying, I have sinned in that I have betrayed the innocent blood. And they said, What is that to us? see thou to that.
Mat 27:5 And he cast down the pieces of silver in the temple, and departed, and went and hanged himself.
There was no repentance for Judas, he had gone too far. He had seen the work of the Holy Spirit and denied the Christ.
Mat 12:31 Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men.
Mat 12:32 And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come.
Judas had witnessed the evidence, that Jesus had the power of God, the fulness of the Holy Spirit. He himself had been filled to go out and heal the sick and cast out demons.
Mat 10:5 These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not:
Mat 10:6 But go rather to the lost sheep of the house of Israel.
Mat 10:7 And as ye go, preach, saying, The kingdom of heaven is at hand.
Mat 10:8 Heal the sick, cleanse the lepers, raise the dead, cast out devils: freely ye have received, freely give.
Judas was the fulfillment of the verses in Hebrews 6, having seen the power of the Holy Spirit and partaken of it, he still loved money more than God, and denied the Christ.
Heb 6:4 For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost,
Heb 6:5 And have tasted the good word of God, and the powers of the world to come,
Heb 6:6 If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.
You have not yet sinned against the Holy Spirit, if you are concerned. If you want to repent and receive Jesus, he wants you to come to him, believing that he is the savior to save you from your sins.
Rom 10:8 But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach;
Rom 10:9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
Rom 10:10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
Rom 10:11 For the scripture saith, Whosoever believeth on him shall not be ashamed.
Call upon the name of Jesus and be saved.
