There is no speech nor language, where their voice is not heard.
Who can utter the mighty acts of the LORD? who can shew forth all his praise?
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.
1 Thessalonians 1:8
For from you sounded out the word of the Lord not only in Macedonia and Achaia, but also in every place your faith to God-ward is spread abroad; so that we need not to speak any thing.
