Jesus chooses Peter to be the keeper of the keys of Heaven. What a witness to forgiveness and reconciliation. Jesus chooses His denier to be the first among His followers.
Forgiveness is immutable. Nothing can trump th3e witness of sins freely forgiven. This is at the heart of Christian witness.
O God, may I be given the strength and courage to forgive as I am forgiven. May I be inspired by the Spirit to offer freely what I have been given freely.
