And this hope will not lead to disappointment. For we know how dearly God loves us, because he has given us the Holy Spirit to fill our hearts with his love.

Rom. 5:5 NLT

What is the greatest act that I can do to break the heart of God? Burn my Bible? Fraternize with the New Atheists? Betray my church and ridicule them to the community? Take a road trip to every dive and house of ill-repute in the South? No, the greatest heartbreak I can cause my Lord is to refuse to believe that he loves me. After the events of the cross and resurrection if I still deny that Christ’s loves me, what more can God do to prove his love?

The greatest sorrow and burden you can lay on the Father, the greatest unkindness you can do to him is not to believe that he loves you.
