There are many who claim to know the difference between good and evil. But, in real life this knowledge in itself does not turn them into overcomers. Now this was my problem too.
To know and not to do is not to know, as some wise man said. But fighting against the truth is a futile thing. Truth wins. The sooner we know the truth and obey it, the better for you and me. God made me to know and obey the truth. May God help you too.
