The Son. Romans 1:4 Following right behind the testimony of the humanity of the Lord Jesus Christ is the testimony of His deity. The central figure of the Gospel is Jesus Christ our Lord. The authentication of His divine nature was established when He was declared to be the Son of God with power when the Holy Spirit raised Him from the dead. Jesus did not become the Son of God by resurrection. Instead, the resurrection of the Lord Jesus proved that Jesus was the Son of God. He had the power to lay down His life and take it again.
The holiness of His Person and the divine Person of the Holy Spirit testify to the One who died for our sins and rose again for our justification. There is no doubt that when we tell people to trust in the Lord Jesus Christ for salvation, we are directing them to the Supreme One of the Universe - the Son of God with power. In contrast to being “the seed of David according to the flesh (His humanity),” Jesus Christ is “designated” the Son of God with power according to, or through, the ministry of the Holy Spirit who has come and dwells in each believer. Our testimony as to the Person and work of our Lord Jesus Christ is a work of the Holy Spirit through us. The authentication of Jesus’s divine nature and the focal point of the proclamation of the Gospel is that Jesus is alive! He has been raised literally and physically from among the dead and receives sinners who “believe in their hearts” that God has raised Him from the dead. Believers confess Him as Lord because they know and experience the life of Christ in them and with them.
He has power over all creation, for He made all things by the word of His power. He has power over all nations to set up or put down as He chooses. He has the power to give and take life, for He has the keys to life and death. He has the power on earth to forgive sins. He has the power to make the Gospel we preach effective in people's souls, for He has commissioned us to preach, and He has all power in heaven and earth. The Gospel that He told us to preach is the power of God unto salvation to everyone who believes. So, we are confident that of His fullness, we have received and can confidently proclaim His Gospel by the grace He gives us.
This passage of scripture summarizes the Gospel message in a precise way. Jesus Christ came as a human to earth by being born a human being. He was a Jew who was in the royal line of David. He died for our sins, even though He was a perfect Person by giving up His life by His own volition and was raised from the dead by taking His life back again. He has opened the door so every person who puts their faith in Him can be saved by His grace and mercy freely given to us. This is what the Book of Romans is about. It is our privilege and responsibility to know and proclaim the Gospel in ways that people of different natures, cultures, nationalities, ages, and languages can understand and believe when they hear the message.
