Joshua 24:16-18

The answer of Israel is just what we might have expected. They have well spoken, said the Lord himself concerning them upon a similar occasion, all that they have spoken. But he who knows what is in the heart, knows what poor, irresolute, weak creatures we are: and, therefore adds, Oh! that there were such an heart in them! Deuteronomy 5:28. Reader! if you know anything of your own heart, you have learnt somewhat of its deceitfulness; and, therefore, will not venture to trust it. I know, says holy Paul, that in me, that is in my flesh, dwelleth no good thing. Romans 7:18.
