Here is a very interesting survey on bribery. Observe.
1. In politics, there is often little or no distinction between a gift and a bribe.
2. We cannot bribe God.
3. Those who use bribery view it as an infallible crutch.
4. Until we lose all sense of shame, we know in our hearts when we have sinned.
If we truly wish to know the state of our heart, there is a better mirror than a pool of water.
James 1:23-25 Good News Translation (GNT)
23 If you listen to the word, but do not put it into practice you are like people who look in a mirror and see themselves as they are. 24 They take a good look at themselves and then go away and at once forget what they look like. 25 But if you look closely into the perfect law that sets people free, and keep on paying attention to it and do not simply listen and then forget it, but put it into practice—you will be blessed by God in what you do.
