Sometimes we pay less attention to things that are of great worth. we are too concerned about so many things that we tend to forget the very fundamental principles of our Faith.

Our Faith is commensurate to the level of spiritual "health" of our hearts.
"FOR WITH THE HEART A MAN BELIEVES UNTO RIGHTEOUSNESS; AND WITH THE MOUTH CONFESSION IS MADE UNTO SALVATION". (Romans10:10)

The heart of a man is the hidden man; the inner man; the spirit of a man.
Anything that finds its way into your inner man defines you ; and if (it is ) evil, defiles you.
[Therefore, there is a need for self examination.
for if you judge yourself, you will not be judged.]

There is a great need to keep your heart with all diligence.(Proverbs 4:23)
know ye not that whatever proceeds out of your heart defines you.? for out of the abundance of the heart a man speaks.
Your heart is what God looks at. that's what He is interested in.(proverbs17:3)
Keep it with all diligence; (like) your life depends on it.
