'In the Spirit' in the Bible

For indeed Christ died for sins once for all, the Just and Righteous for the unjust and unrighteous [the Innocent for the guilty] so that He might bring us to God, having been put to death in the flesh, but made alive in the Spirit;

For this is why the good news [of salvation] was preached [in their lifetimes] even to those who are dead, that though they were judged in the flesh as men are, they may live in the spirit according to [the will and purpose of] God.
