No where in that passage that says it was planned. It says He revealed His glory but doesn’t say it was planned. It’s not a big deal in the overall scheme of things so no sense in continuing this.
So, my friend, we have the Jesus (the Lamb of God) at a Wedding Feast where His Wine (blood) has made everything work out.
It’s a prefigurement of the eternal.
And, this is no accident. It does say it was done by one person. It says HE revealed his glory. It doesn’t say “Mary revealed His glory.” It also says this miracle was the first. And it says that the “hour” to which he referred was the hour of his passion, when He wouldn’t divert from the cup He had to drink. His ministry had already begun at his baptism.
And this at the end of John: “30 Jesus did many other miraculous signs in the presence of his disciples, which are not recorded in this book. 31 But these are written that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.”
