The clearest way to know God is to listen to what he says!
One of the first things that we learn about God in the opening Chapter of the Bible is that he talks. ‘In the beginning God created’ and how did he do that? By his word ‘And God said: ‘Let there be light’…., and then God said: ‘Let there be an expanse between the waters…, and then God said: ‘let there be sky’… and so it goes on for seven days (Genesis 1:1-2:3).
Each of the special acts of creation come about by the word of God. What he creates is new and wonderful and he does that by uttering his words.
If the significance of that is lost on you, give it a go! Test the power of your words. Create something by your words and only your words – ‘Let there be a ham sandwich’! How did you go? I think I can guess!
