He had no spot or blemish. We are not perfect, but we are loved . In Scripture, wrongdoing is explained as causing spots. How gracious, loving and fair of God to reveal this to us. Except for Jesus, all of us have spots.
Spots are there, but they are only spots, mars.
God sees more than our spots, and He loves the person He sees. He can wash away our spots. He says His washing makes us whiter than snow. It falls gently. It sparkles in the light, reflecting the light of heaven.
