Matthew 26:26 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;
To ‘eat and drink’ in scripture symbolises to ‘do the works of’
The wicked engage in acts of wickedness and violence..
Proverbs 4:14 Enter not into the path of the wicked, and go not in the way of evil men… 17 For they eat the bread of wickedness, and drink the wine of violence.
Men should live by the commandments of God.
Matthew 4:4… Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God.
Jesus’ ‘food’ was to do the will of God.
John 4:32 But he said unto them, I have meat to eat that ye know not of… 34… My meat is to do the will of him that sent me, and to finish his work.
The believer’s ‘food and drink’ is to imitate the life of Christ and live by his precepts..
John 6:53… 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.
Those who believe the gospel and are baptised into Christ are required to live by his commandments.
John 15:14 Ye are my friends, if ye do whatsoever I command you.
Luke 6:46 And why call ye me, Lord, Lord, and do not the things which I say?
James 1:22 But be ye doers of the word, and not hearers only, deceiving your own selves.
The act of sharing bread and wine in remembrance of Christ’s sacrifice represents the living of our lives by his commandments.
Thus, when we break bread and drink wine, we are to examine ourselves to see whether we truly are obeying his commandments. If we are not, then we eat and drink condemnation to ourselves.
1 Corinthians 11:28 But let a man examine himself, and so let him eat of that bread, and drink of that cup. 29 For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord’s body.
This doesn’t mean that we can live sinless lives – but if we are making a determined effort to live by Christ’s commandments (i.e. walking in the light), our sins will be forgiven by confession in prayer.
1 John 1:7 But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin. 8 If we say that we have no sin, we deceive ourselves, and the truth is not in us. 9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
I hope this helps
