Psalms 19:3

There is no speech nor language, literally, "Not is there speech, and not are there words," where their voice is not heard. The message proclaimed by the inanimate creatures everywhere and at all times is of a nature to be clearly discernible to all ears which are not deliberately stopped up. God has always manifested Himself, made Himself known in such away as to be seen and recognized by all who had their eyes and ears open. There is no excuse if men have not understood God's eternal power and Godhead, Romans 1:20.
