But God shows his love for us in that while we were still sinners, Christ died for us (Romans 5:8 ESV). 

Our Father who are in heaven, we your children are often troubled in mind, hearing within us at once the affirmations of faith and the accusations of conscience. We are sure that there is in us nothing that could attract the love of One as holy and as just as you are. Yet, you have declared your unchanging love for us in Christ Jesus.

If nothing in us can win your love, nothing in the universe can prevent you from loving us. Your love is uncaused and undeserved. You are the reason by which we are loved. Help us to believe the intensity, the eternity of the love that has found us. Then love will cast out fear; and our troubled hearts will be at peace, trusting not in what we are, but in what you have declared yourself to be. Amen.
