Some people are grappling with ugly in their heart. The kind of ugly that is in each of our hearts, whether saved or not. Doubt about God’s power to transform can inbred characteristics (“that’s just the way I am”). God is adamant that He can changes lives–and desires to do so! If you’re struggling with the ugliness of sin in your own life–whether that’s yelling, holding a grudge, being stingy with others, or drowning your sorrows in daily errands–there is hope in Jesus. 
Romans 12:2.
 Do not conform to the pattern of this world, but be transformed by the renewing of your mind.Then you will be able to test and approve what God's will is—his good, pleasing and perfect will.
2 Corinthians 5:1 
Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new.
