In suggesting that God might be willing to overlook the imperfect understanding of "His" little ones, this old legal maxim came to mind: "Ignorance of the law is no excuse." For those who view God as a harsh and uncompromising entity, this traditional attitude toward lawbreakers perfectly reflects God's attitude towards humanity with regard to our many sins.
However, when Jesus Christ was hanging on the cross, he is purported to have said: "Father, forgive them, for they do not know what they are doing." (Luke 23:34, NIV, emphasis mine) Most folks rightly focus on the amazing compassion in Christ's request that God would forgive his murderers. But how many of us have read this Scripture dozens of times and completely overlooked the justification that Christ employed (they don't know what they're doing) in making his request of God. Jesus said that they should be forgiven because of their imperfect understanding of their actions.
Don't we all recognize these almost instinctive impulses towards compassion and clemency in how we treat our own little ones? We understand that they don't yet fully understand the consequences of their actions, and we are ready to overlook a good many things because of that. Isn't it interesting that our Savior appealed to the same reasoning in what he asked of his Father?
