In the new testament, where Jesus says to his deciples, I will return and baptise you.. not even paraphrasing here, just pointing to what he said generally.. (sorry) I will send my spirit, or the spirit who will cause you to be able to do all of the things that I have done. So, in reading the new testament you will find where Jesus points that out and that also in  the Eccles. part where it talks about standing,and standing firm and then standing, at the end it says something to the order of; and always pray in the spirit continually for the saints (the body of christ, the church body). Ephesians 6:10-18 New International   18 And pray in the Spirit on all occasions with all kinds of prayers and requests.  With this in mind, be alert and always keep on praying for all the Lord’s people. 6:10-18 (niv)
