In Acts 3:1 Peter and John were going to pray at 3pm
In 1 kings 18:36-38, Elijah called on God at 3pm and fire fell from heaven
In Daniel 9:21, as Daniel prayed, around 3pm, Angel Gabriel appeared to him
In Acts 10:30, as Cornelius prayed, an angel appeared to him.

And the greatest of all, in Matthew 27:46-52, Mark 15:33-36, and Luke 23:44-46; around 3pm in the afternoon – Jesus said IT IS FINISHED, Jesus DIED! the veil in the temple was torn from top to bottom, and both spiritual and physical darkness were lifted; and graves were supernatural broken

What a POWERFUL HOUR 3PM is!!!
The hour of apostolic supplication! Shanda!
The hour of prophetic intercession! Yebaba!
The hour of the God that answers by fire! Kabaya!
The hour of angelic visitation! Tokondoye!
The hour of abolishing the old covenant! Katabaya!
The hour of the greatest deliverance! Kayaya!

The hour of the greatest declaration – It is finished! Scatter-baya!
The hour of redemption! Gloraaaaay!
The hour of salvation! Ayayayaya!
The hour of Calvary! Kai!
The hour of grave destroying resurrection! Kondobaya!
You see how one can form a doctrine out of things?

I have read of people who saw these things and decided to start praying at 3pm WITH GREAT RESULTS.
I won’t be surprised if someone copies the foregoing and turns it into a “powerful” message…
But is there anything special about the time – 3pm?
NO.

They got results because they prayed with faith. They got results because God overlooked their ignorance and honoured their faith. Unless God told them specifically to pray at that time, had they prayed at any other time in the day or night in faith and obedience; they would have gotten great results
Fire has come down from heaven at other times
Angels have visited men at other times
God appeared to Solomon at night and He visited Abraham in the heat of the day
Apostles prayed at other times
Prophets prayed at other times.
And the Lamb of God was slain from the foundation of the world! The works were finished then.

So there is something special at being led to pray at a particular time. Obedience is key.
There is something special about choosing a particular hour of prayer even though you pray at other times. Consistency is key.
But there is no special mystery to any particular time of the day or of the night.
It is the effectual fervent prayer of a righteous man that avails much. All prayers said in faith and obedience are mysterious, powerful and effective.

The ninth hour of the day, and the ‘time of the evening sacrifice’ or ‘evening oblation’ (in the Bible) both refer to 3pm.

God Bless You.
