Evidence Of A Hard Heart

The Bible describes something called a hard heart. The heart is the sum total of our inner most being. Here are some evidences of a hard heart.
1. They interpret all information(especially moral) negatively.
2. They spin every situation so that they are innocent and you are guilty, or they are the victim and you(or somebody) owes them.
3. Everybody who opposes them needs to change not them...including God. Oh, by the way, they found many things wrong or mistakes in the Bible.

BAD NEWS- Before Trusting Jesus for salvation

Ephesians 4:17 So this I say, and affirm together with the Lord, that you walk no longer just as the Gentiles(non Christians) also walk, in the futility of their mind, 4:18 being darkened in their understanding(their view of reality is wrong), excluded from the life of God because of the ignorance that is in them, because of the hardness of their heart 4:19 and they, having become callous(don't care about sin), have given themselves over to sensuality for the practice of every kind of impurity with greediness.

GOOD NEWS- The transforming power of God once you become Christian

4:20 But you did not learn Christ in this way, 4:21 if indeed you have heard Him and have been taught in Him, just as truth is in Jesus... (NASB - sent from CadreBible)

When you put your faith, hope and love in Jesus(who he says he is and what he did for you) he gives you his righteousness, a new heart and a new identity...now being "In Christ".
