I may be theologically off-base, but man did not know good and evil until he eat the fruit from the tree of knowledge as recorded in Genesis. Since then he has known good and evil and was cast out of the garden into the world. Could this be the conscience you allude to?
If so, then we have a conscience (foreknowledge of good and evil) given to us by GOD. And against our better judgement we are persuaded (tempted or corrupted or deceived) by the world (Satan) to do evil. It is our conscience that guides us toward GOD and away from evil.
As little children we are conceived with this knowledge, which is why the abortionist cannot wait for them to be born. How many saints has Satan aborted in the womb? How many of GOD’s little children has he deceived after they are born? Jesus warned us, the world is evil and we have all sinned.
=========================================
1. Amen.
2. Yes, indeed.
3. Satan is doing HIS job, isn't he? Jesus DID warn us. Our best course of action is to stay VERY close to Jesus.
