'Spirit' in the Bible

For I have known that this shall fall out to me for salvation, through your supplication, and the supply of the Spirit of Christ Jesus,

Only worthily of the good news of the Christ conduct ye yourselves, that, whether having come and seen you, whether being absent I may hear of the things concerning you, that ye stand fast in one spirit, with one soul, striving together for the faith of the good news,

If, then, any exhortation is in Christ, if any comfort of love, if any fellowship of spirit, if any bowels and mercies,

And I hope, in the Lord Jesus, Timotheus to send quickly to you, that I also may be of good spirit, having known the things concerning you,

for we are the circumcision, who by the Spirit are serving God, and glorying in Christ Jesus, and in flesh having no trust,
