Jeremiah 17:9 KJV
The heart is deceitful above all things , and desperately wicked: who can know it?
Proverbs 14:12 KJV
There is a way which seemeth right unto a man, but the end thereof are the ways of death.
Romans 12:2 KJV
And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.
Romans 5:5 KJV
And hope maketh not ashamed; because the love of God is shed abroad in our hearts by the Holy Ghost which is given unto us.
James 1:22-25 KJV
But be ye doers of the word, and not hearers only, deceiving your own selves.  For if any be a hearer of the word, and not a doer, he is like unto a man beholding his natural face in a glass:  For he beholdeth himself, and goeth his way, and straightway forgetteth what manner of man he was.  But whoso looketh into the perfect law of liberty, and continueth therein , he being not a forgetful hearer, but a doer of the work, this man shall be blessed in his deed.
