Failure is an event not a person or destiny.

Peter's Denial - John 18
When fear crept in Peter lost who he was in a moment.

Peter Restored - John 21
Our failures do not define us. What matters is what happens next.
Humility leads to a true understanding of Love.
When we love the Lord with all our heart, mind, soul and strength we will begin to fail less and discover our purpose more.
God doesn't stop pursuing you because of your failures, and God doesn't want us to stop pursuing HIM when we fail.
