Believers can be assured they possess the Holy Spirit by their faith in Christ and His work in their lives.
The presence of the Holy Spirit is a crucial assurance for believers. Romans 8:9 states that 'if any man have not the Spirit of Christ, he is none of His,' indicating that possessing the Spirit is indicative of true faith. Furthermore, the Holy Spirit is revealed in the life of a believer by leading them to repentance, strengthening their faith, and enabling them to live in obedience to Christ. This transformative work is evidence of the Spirit's presence, confirming that they are indeed children of God. The works of the Spirit in guiding and sustaining believers in their faith are consistent with the promises made by Christ regarding the Holy Spirit's role in the believer's life.
