Why should we be ashamed of the rainbow when it is a promise from God to everyone on the earth? Lucas is brave and called by God at a very young age, only he does not realize it yet. Lucas is not afraid to speak the truth boldly, and he rather enjoys it. He is teaching his classmates, and his ministry is just beginning. Lucas does not draw back nor backdown, and this is required from all of us who believe in the gospel of Jesus Christ, for it is the power of God.
