On the cross we see the invincible forgiveness of Jesus. Even as they
drove the nails through him, he prayed, “Father, forgive them; for they
know not what they do. (Luke 23:34). It is as if Jesus said, “No matter
what you do to me, I will still forgive.” If in Jesus we see the mind of
God fully displayed, it means that there are no limits to the love, the
grace, the forgiveness of God. We see Jesus on the cross embodying the
message of divine forgiveness which he brought to men.
