The gospel is the power of God unto salvation. "For our gospel did not come to you in word only, but also in power, and in the Holy Spirit and much assurance" (1 Thessalonians 1:5). Confessing Jesus as Lord is the work of the Holy Spirit in us (1 Corinthians 12:3). The Holy Spirit enables us to repent and believe on the Lord Jesus Christ.
The gospel in power is God leading us to repent (Romans 2:4). This change of mind enables is turning from unbelief, that we may turn to the Lord by faith. We are enabled to believe on the Lord Jesus Christ to be saved (Acts 16:31).
The gospel the power is God changing our hearts, which is our mind, will, and emotions. It is the power of the Holy Spirit. Our conversion is made possible when the Holy Spirit works in us through regeneration, also known as new birth. Conversion is through the gospel of our Lord Jesus Christ (1 Corinthians 15:1-4). The word of the gospel is the Holy Spirit's instrument to transform our lives.
The gospel in power is God transforming our minds (Romans 12:1-2). It can never be accomplished without the Spirit of God working in us. Without the gospel in power, we may spend a lifetime in study without understanding the truth of God. The renewal of the mind is transformation by God's power in the gospel.
