These verses cause me to ponder and look into my own heart.  

Jesus warns his audience that not everyone who professes to be a disciple of Jesus really is one. Lip service doesn’t seal the deal. Even works done in Jesus name don’t seal the deal. It’s ultimately a matter of the heart. Jesus wants our hearts to be set on him. He wants to truly know us.

I want to know Jesus. I want him to tell me well done, not depart from me. This takes a total commitment to Christ. One that only total denial of self will allow. It is a continual struggle and I feel like I’m losing alot of times. My strength and help comes from the Lord though. If I don’t deny him, and stay true to him, surely he’ll stay true to me. ( 2 Timothy 2)
