'Live in the Spirit' in the Bible

Because Christ also suffered for sins once, the righteous for the unrighteous, that he might bring us to God; being 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.
