This is a prayer that could be found in probably every missal. I think It would be a wonderful thing to share with you. It helps us contemplate on the immense love and mercy Jesus has for us and our ingratitude towards Him.
Before Thine eyes O Lord, we bring our sins and we compare them with the stripes we have received.
If we examine the evil we have wrought, what we suffer is little, what we deserve is great.
what we have committed is very grievous, what we have suffered is very slight.
We feel the punishment of sin, yet withdraw not from the obstinacy of sinning.
Under Thy lash our inconsistency is visited, but our sinfulness is not changed.
Our suffering soul is tormented, but our neck is not bent.
Our life groans under sorrow, yet mends not in deed.
If Thou spare us, we correct not our ways: if Thou punish, we cannot endure it.
In time of correction we confess our wrong doing: after Thy visitation we forget that we have wept.
If Thou stretchest forth thy hand, we promise amendment, if Thou witholdest the sword, we keep not our promise.
If Thou strikest, we cry out for mercy, if Thou sparest, we provoke Thee to strike.
Here we are before Thee, O Lord confessedly guilty: we know that unless Thou pardon we shall deservedly perish.
Grant then, O almighty Father, without our deserving it and the pardon we ask; Thou madest out of nothing those who ask Thee. Through Christ Our Lord. Amen.
