When I came to you, brothers, it was not with any show of oratory or philosophy, but simply to tell you what God had guaranteed. During my stay with you, the only knowledge I claimed to have was about Jesus, and only about him as the crucified Christ. Far from relying on any power of my own, I came among you in great ‘fear and trembling’ and in my speeches and the sermons that I gave, there were none of the arguments that belong to philosophy; only a demonstration of the power of the Spirit. And I did this so that your faith should not depend on human philosophy but on the power of God.
Jesus said to his disciples, ‘You are the salt of the earth. But if salt becomes tasteless, what can make it salty again? It is good for nothing, and can only be thrown out to be trampled underfoot by men.
‘You are the light of the world. A city built on a hill-top cannot be hidden. No one lights a lamp to put it under a tub; they put it on the lamp-stand where it shines for everyone in the house. In the same way your light must shine in the sight of men, so that, seeing your good works, they may give the praise to your Father in heaven.’
