"... the gospel He promised beforehand through His prophets in the Holy Scriptures..." (Rom. 1:2)
Paul had talked about the messenger.
Paul was a servant of God.
He was His ambassador.
He had been set apart by God to carry His Gospel to a lost world.
Paul then talked about his message.
Paul’s message was centered in the Person of the Lord Jesus Christ.
Jesus Is The Promised One (Rom. 1:2)
The Gospel involves the death and resurrection of the Lord Jesus.
It was not an afterthought of God.
God had been declaring that His Son would come and that His Son would die for the sins of humanity.
The Gospel is not a new thing.
The Old Testament Scriptures speak of the Lord (John 5:39).
The sacrifice of the Messiah is plainly foretold in the Old Testament (Isa. 53:1-12).
The Old Testament is filled with types and symbols that point to the coming Savior.
Adam, the Ark, the Manna, the Tabernacle, the Sacrificial system, etc. all pointed ahead to the One who was to come.
Every little lamb that was killed in sacrifice gave testimony to the One who was coming later.
Jesus is the promised One.
He is our promised Lord and Savior.
