“Eat, drink and be merry” is an expression usually associated with gluttony and hedonism.
However, in spite of the negative association with it there is a holy application of this verse, if you will.
Firstly, Christ has invited us to feed off of Him, the Bread of Life (1 Cor. 11:24).
Secondly, He has further invited us to drink of His saving blood (1 Cor. 11:25).
Lastly, we are instructed to rejoice in His salvation (Hab. 3:18) and in our weaknesses (2 Cor. 12:9, 13:9), and to maintain thankfulness in and for everything (Eph. 5:20). These develop in us a merry heart which is good medicine for the body and the soul (Prov. 17:22).
By these standards, in a holy current that flows opposite of the world’s, believers can choose to honor God by “eating, drinking and being merry” every day.
I [Myself] am this Living Bread that came down from heaven. If anyone eats of this Bread, he will live forever; and also the Bread that I shall give for the life of the world is My flesh (body).
Then the Jews angrily contended with one another, saying, How is He able to give us His flesh to eat?
And Jesus said to them, I assure you, most solemnly I tell you, you cannot have any life in you unless you eat the flesh of the Son of Man and drink His blood [unless you appropriate His life and the saving merit of His blood].
1 Corinthians 11:24-26
And when He had given thanks, He broke [it] and said, Take, eat. This is My body, which is broken for you. Do this to call Me [affectionately] to remembrance.
Similarly when supper was ended, He took the cup also, saying, This cup is the new covenant [ratified and established] in My blood. Do this, as often as you drink [it], to call Me [affectionately] to remembrance.
For every time you eat this bread and drink this cup, you are representing and signifying and proclaiming the fact of the Lord’s death until He comes [again].
2 Corinthians 12:9
But He said to me, My grace (My favor and loving-kindness and mercy) is enough for you [sufficient against any danger and enables you to bear the trouble manfully]; for My strength and power are made perfect (fulfilled and completed) and show themselves most effective in [your] weakness. Therefore, I will all the more gladly glory in my weaknesses and infirmities, that the strength and power of Christ (the Messiah) may rest (yes, may pitch a tent over and dwell) upon me!
2 Corinthians 13:9
For we are glad when we are weak ([a]unapproved) and you are really strong. And this we also pray for: your all-round strengthening and perfecting of soul.
And in that day the Lord God of hosts called you to weeping and mourning, to the shaving off of all your hair [in humiliation] and to the girding with sackcloth.
But instead, see the pleasure and mirth, slaying oxen and killing sheep, eating flesh and drinking wine, [with the idea] Let us eat and drink, for tomorrow we die!And the Lord of hosts revealed Himself in my ears [as He said], Surely this unatoned sin shall not be purged from you until [you are punished–and the punishment will be] death, says the Lord God of hosts.
Yet I will rejoice in the Lord; I will exult in the [victorious] God of my salvation!
At all times and for everything giving thanks in the name of our Lord Jesus Christ to God the Father.
1 Thessalonians 5:18
Thank [God] in everything [no matter what the circumstances may be, be thankful and give thanks], for this is the will of God for you [who are] in Christ Jesus [the Revealer and Mediator of that will].
Through Him, therefore, let us constantly and at all times offer up to God a sacrifice of praise, which is the fruit of lips that thankfully acknowledge and confess and glorify His name.
A cheerful heart is good medicine, but a crushed spirit dries up the bones.
