As sinful creatures, we cannot understand these words in their fullness. Christ was filled up with both grace and truth. His Grace Grace is a wonderful word. We are saved by grace, kept by grace, and our faith is by grace. Grace is overwhelming kindness, good-will, and favor.
Grace is a special kind of tenderness.
You can see it in the Gospels as He deals with mankind. He heals and cures all manner of hurt. Parents brought their children to Him and He accepted them. God's grace manifests itself in His love. God is love.
