'In the Spirit' in the Bible

For I, verily, being absent in the body, but present in the Spirit, have already, as if present, judged him who so wrought this;

And such were some of you; but ye were washed, but ye were sanctified, but ye were justified in the name of the Lord Jesus, and in the Spirit of our God.

Wherefore, I make known to you that no one speaking in the Spirit of God, says, "Jesus is accursed"; and no one can say, "Jesus is Lord," except in the Holy Spirit.

For he that speaks in a tongue speaks not to men, but to God; for no one understands; but in the spirit he speaks mysteries.
