Understand the gospel is the good news of God through Christ. The Lord Jesus died for our sins. The power of the Holy Spirit raised Jesus from the dead. Jesus is "declared to be the Son of God with power according to the Spirit of holiness, by the resurrection from the dead" (Romans 1:4).
Understand the gospel through the Holy Spirit. He has the power to change our hearts, that is our thoughts, desires, and emotions. The Holy Spirit makes a change in us which is real and permanent. That's the gospel in power (1 Thessalonians 1:5).
Understand the gospel is salvation in Christ alone. We confess is Lord, because we believe He is risen from the dead (Romans 10:9). That's the power of the Holy Spirit in you. The gospel is the power of God unto salvation for all who believe. The power of the Holy Spirit is found through the gospel of Jesus Christ (Romans 1:16).
Understand the gospel is not forced upon you against your will. However, through the gospel you are empowered to do God's will. "For it is God who works in you both to will and to do for His good pleasure" (Philippians 2:13). Through the gospel, your will is set free from the bondage of sin to do the will of God. That's the power of the gospel of Jesus Christ, through the Holy Spirit.
