'Spirit' in the Bible

For I know that this shall turn out to my salvation, through your supplication and the supply of the Spirit of Jesus Christ,

Only let your manner of life be worthy of the gospel of Christ: that, whether I come and see you and be absent, I may hear of your state, that ye stand fast in one spirit, with one soul striving for the faith of the gospel;

If there is therefore any exhortation in Christ, if any consolation of love, if any fellowship of the Spirit, if any tender mercies and compassions,

for we are the circumcision, who worship by the Spirit of God, and glory in Christ Jesus, and have no confidence in the flesh:

The grace of the Lord Jesus Christ be with your spirit.
