What would it have been like if the Holy Spirit had not descended upon the apostles?
Surely they would have had good and tragic memories of Jesus.
Probably some would have written down the most interesting events in the form of a diary. Surely, the truth about Jesus would go from mouth to mouth and evolve so that Jesus would become a sort of half truth.
Certainly the Christian religion might have happened to promise a lot, but not give any guarantees. Then today we could have read about Christianity in books of ancient times. But what about today, if it was told to us that the Holy Spirit was not here?
Probably nothing. Maybe it would cause some confusion in our being a Christian. Probably our faith would look like this so far. God is the Father, Jesus is with us, and we have Mary and the saints. We have a lot of holy masses, and celebrations and we have churches. Nothing would have changed.
Without the Holy Spirit, Christianity would be dry. It would be like a museum exhibit. Its only value is that it recalls the past, but it is useless.
Someone once said, that many people "drink" Christianity without ground coffee. So, if you throw a few coffee beans into a cup with boiling water - it is still a cup of water. Until you "grind" those coffee beans, you do not bring out the flavor. Many people, unfortunately, do not even know that Christianity might be interesting with a really deep flavor.
The Holy Spirit is the one who "grinds" our Christianity bringing out the flavor. But we have to let it.
None of us will become rich if we only go to the bank for a walk and then watch.
None of us will become rich in faith if we are merely passive observers and listeners.
We need the Hoy Spirit who will work for us. Who, without our knowledge will prompt us to what we have to do and even to do more.
Very often, the Holy Spirit is compared to the wind. We have no control over this element, but the wind has control over us.
If we try to understand the action of the Holy Spirit in this way, we will also find our Christianity in the wind, but if we want to catch the Holy Spirit like a "wind in our sails", we will always be pushed to do good things. Then our faith will be alive and tasted not only by us, but by others as well.
