He answered them, "He who made me well, the same said to me, 'Take up your mat, and walk.'"
Aren't you glad the Father works on the Sabbath day? What if God took off every Sabbath day? Think of all the mess the world would be in, trying to recover from God taking a rest every Sabbath day. He that keeps Israel neither slumbers nor sleeps. God doesn't take any day off. God is working in the lives of His people all the time. And so Jesus said, "Look, my Father works, and so I work."
