(Which he had promised afore by his prophets in the holy scriptures,)
This verse here is speaking about the gospel or good news (happy news) that is mentioned in verse 1.
Paul is telling us two things about the good news:
1. It was promised before it happened
2. It is found in the Scriptures.
Point 1 is just remarkable – no other religion has a leader who fulfills prophetic word after prophetic word after prophetic word. We knew hundreds of years before Jesus was ever born that He would be born in Bethlehem, born in the lineage of David, born to a virgin, that He should grow in grace, heal the sick, be a light to the darkness, preach the good news, open blind eyes, preach liberty to the captives. We knew He would be nailed to a cross, with pierced hands and feet, surrounded by evildoers, buried by a wealthy man, and that He paid the price for our sin and our iniquities.
There are 333 prophetic words just about Jesus’ first coming in the Old Testament. Here are just a few for your study time:
Old Testament Prophecy: Isaiah 7:14
Fullfillment in Jesus: Matthew 1:18,22,23
Old Testament Prophecy: Micah 5:2

If you think about it this proves beyond the shadow of a doubt to anyone with an open mind that Jesus is Lord and that God is real.
The second thing Paul tells us about the good news is that it is found in Scripture. Your source of power, your source of life is not found in the TV, not found in church, not found in prayer, not found in friends, not found in emotions, not found in the latest worship song, but found in the Scriptures.
If you want to be separated to the happy news and be a happy person spreading love, joy, healing and prosperity wherever you go: get in the Scriptures, that is where the news is found.
Glory and freedom,
