Conscience
It is not as hard to know what is right to do as to do what you know is right. (Source unknown)
As children grow, they begin to develop a sense of right and wrong. That’s what parents and teachers work for, lovingly correcting wrong and encouraging right. But knowing the difference between them is one thing; choosing the right over the wrong may be quite another. The critical issue is whether they have developed a conscience and learned to listen and follow it.
The purpose of my instruction is that all believers would be filled with love that comes from a pure heart, a clear conscience, and genuine faith (1 Timothy 1:5).
