In my own opinion conscience can be human behaviour and human feelings at a particular time.
We have right and wrong conscience. The right conscience is from God while the wrong one is from the evil spirit (Satan).
The right conscience is the behaviour of a particular person in a very good way at a particular time i.e doing the right thing at the right time while the wrong conscience is the the wrong thing at the right time. It is a pity that minority of we human beings are having the right conscience i.e. God while the majority are having wrong conscience one being monitored controlled by the devil.
This type of wrong behaviour is peculiar to people of nowadays i.e. the working class people. We work harder in our personal work than any other work, we always say one proverb ("a kii se ose oba laagun") in yoruba, translated, 'we musn't work too diligently on a paid job. This is against the will of God for us It is what you sow that you will reap.
Secondly you've forgotten that your children are elsewhere to reap what you have sowed. So try to sow good so that good can be perfected in your life and the life of your children in future and elsewhere.
Let the right conscience always be your watch word everywhere you are and you will see how god will bless you and your family.
