In short
The Holy Spirit is God, the third Person of the Trinity, given to live within everyone who trusts Jesus. He comforts, guides, convicts, and transforms, making the presence of God real in a believer's daily life.The Spirit is not a force but a Person, fully God, sent by Jesus to be with His people forever. He assures us we are God's children, helps us pray, and grows the character of Christ in us, love, joy, peace, and more.
When you come to Jesus, you are not left alone; God Himself comes to dwell with you.
