Romans 10:17, So then faith comes by hearing and hearing by the Word of God.
Life itself is faith and so everything we set out to do everyday is based on the faith we have about something and so our lives revolves around faith. But faith gets strengthened and weakened based on lots of things and one of things are the things we hear.
Imagine how disappointed you may feel when you hear lots bad things about someone you trusted so much and perhaps would never has associated with an event or activity. Not that you judge the person but before you even take a step to investigate that feeling has already crawled up inside.
This is because word are powerful tools and the hearing sense is one of the ways to get to the soul. And so we have to meticulous the things we expose ourselves to hearing. Instead the bible says faith comes by hearing of the Word of God and so brethren as we start a new month, expose yourself to hearing the word of God that you may grow in the faith of the Lord.
