A fifth grader would define it as "truth that is authentic." Actually a good answer in a humorous way. More importantly, both describe God as they are of God. And as His children we are called to live it as lights of Christ and model authentic truth out of love. A lot of people in the world need this right now! This is what beats the evil one in the daily spiritual battles of life. We need to be the real us and and live the truth. Praise God!
