'In the Spirit' in the Bible

If then there is any comfort in Christ, any help given by love, any uniting of hearts in the Spirit, any loving mercies and pity,

let nothing be in the spirit of strife or vain glory, but, in lowliness of mind, each esteeming the other as more excellent than themselves;

For we are the circumcision, which worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh.
