We often hear these saying but ignore them. A guideline is useless if we do not use it. Even though we are interested in what is best for ourselves we have a tendency to think we can get away with things.
The scriptures can be like our clichés. We hear them but ignore them. The Bible is very specific about our need to act on what the bible says. It says, Do what God's teaching says; when you only listen and do nothing, you are fooling yourselves” James 1:22 (NCV). Be the doer God called you to be.
