Many years ago, John, as a Lay Reader, preached a sermon on Psalm 139. I have never forgotten it and this Psalm has remained my favourite ever since. Psalm 139 O Lord, You have searched me out and known me You know when I sit down and when I rise up, You understand my thoughts afar off. You search out my path and my lying down, and know all my ways. For there is not a word in my tongue, but, lo, O LORD, You know it altogether. You have beset me behind and before, and laid your hand upon me. Such knowledge is too wonderful for me; it is high, I cannot attain it. Where shall I go from Your Spirit? or where shall I flee from Your Presence? If I ascend up into heaven, You are there: If I make my bed in hell, behold, You are there. If I take the wings of the morning, and dwell in the uttermost parts of the sea; Even there shall Your hand lead me, and Your right hand shall hold me. If I say, surely the darkness shall cover me; even the night shall be light about me. The night shines as the day: the darkness and the light are both alike to You. For You have possessed my reins: You have covered me in my mother's womb. I will praise You; for I am fearfully and wonderfully made: marvellous are Your works; and that my soul knows right well. My frame was not hid from You, when I was made in secret. How precious also are Your thoughts unto me, O God! how great is the sum of them! If I should count them, they are more in number than the sand: when I awake, I am still with You .
