The book of John 2; the wedding in Cana, Galilee is interesting for two reasons.
The first being understanding and knowing the unfathomable depth of Gods love towards us as illustrated by Mary instructions to the servants despite Jesus reply that His time has not yet come…See my article titled…“How deep is His love? Do you know“
The second is the crux of this Article and it finds its expression in John 6:63 which reads thus “It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.
Now Mary says in John 2:5 to the servants “… Whatsoever he saith unto you, do it.”. How did Mary know that whatsoever Jesus says will happen?
This is my take; she had spent a lot of private and quiet time with the Word(Jesus, her Son, her boy) and had witnessed him say things and they always come to pass.
She has/had spent quality time studying and mediating on His words and discovered that even as a child He spoke with authority.. Mark 1:22…“And they were astonished at his doctrine: for he taught them as one that had authority, and not as the scribes.
She must have “seen” His Words come to pass very quick and immediate on humans…Mark 1:42…“And as soon as he had spoken, immediately the leprosy departed from him, and he was cleansed”
And on non humans I.e…cursing the fig tree…Mark 11:20 “And in the morning, as they passed by, they saw the fig tree dried up from the roots.”
Mary probably had read Isaiah 55:11 which says “so is my word that goes out from my mouth: It will not return to me empty, but will accomplish what I desire and achieve the purpose for which I sent it.” And then heard Jesus say in Matthew 24:35 … “Heaven and earth will pass away, but my words will never pass away.”
God’s Word Works regardless of situations and circumstances…all it requires from you is faith… Hebrew 4:2…“For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard it.”
King of kings, Lord of lords, Sovereign Lord and Maker of all things…I pray for grace for every Believer to study, meditate and live on your word because Your Word Works ALL THE TIMES….in Jesus name…Amen
