Pray in Spirit and Truth

Joh-14:16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; 

Rom-8:26 Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered.

1Th-5:17 Pray without ceasing. 

2Th-3:1 Finally, brethren, pray for us, that the word of the Lord may have  free course, and be glorified, even as  it is with you: 

1Ti-2:8 I will therefore that men pray every where, lifting up holy hands, without wrath and doubting.
