Excellent video on the blindspot of thinking we are good. This was a big one for me too.
Jeremiah 17:9 King James Version (KJV)
9 The heart is deceitful above all things, and desperately wicked: who can know it?
Everyone has a deceitful heart: Christians and non-Christians. The only thing we are really able to do is to try to be honest and meekly ask God to help us obey the word of God. This is the fastest way I know for you to be saved: be really honest with God and cry out for help.
