The Holy Spirit is in every believer in the Lord Jesus Christ (Acts 2:38-39; Romans 8:9). He will never leave you nor forsake you (John 14:16-17). You are sealed with the Holy Spirit until the day of redemption, at the coming of Christ (Ephesians 1:13, 4:30). God, who began a good work in you, will perform it until the day of Christ (Philippians 1:6; 2:13).
The Holy Spirit is in all who confess Jesus Christ is Lord (1 Corinthians 12:3). He works in you according to God's good will. The Holy Spirit changes our hearts (Romans 2:28-29). That's called regeneration or new birth. He gives you a renewed will with a desire to do God's will.
The Holy Spirit is in us through the abiding gifts of faith, hope and love. "And now abide, faith, hope and love, these three; but the greatest of these is love" (1 Corinthians 13:13). We are saved by faith in Christ. We have hope in Christ for our glorification. We shall receive a glorified body like that of the risen Christ (1 John 3:2). We can never be separated from the love of God (Romans 8:38-39).
The Holy Spirit is in the mind, will, and emotions of every believer. He is doing more in you than you understand. He is always doing more than you ask or think (Ephesians 3:20). The Holy Spirit works in believers to bring glory to the name of the Lord. The Holy Spirit gives us the ability to minister to others and to witness in power for Christ (Acts 1:8; 1 Peter 4:10-11).
