Luke 13:16

Luke 13:16 - Then should not this woman, a daughter of Abraham, whom Satan has kept bound for eighteen long years, be set free on the Sabbath day from what bound her?”

When Jesus would heal on the Sabbath He would always run into opposition. There would always be someone there who would be caught up in the rules and regulations of the law and not the spirit of the law.
This time it was the synagogue ruler. He actually went as far as to ask the people not to come to Jesus on the Sabbath. “There are six days for work,” he said, “So come and be healed on those days, not the Sabbath.”
In reading this it seems crazy that they would purposefully try to keep people from receiving healing from Jesus. Jesus would never stop people from coming to Him.
Jesus says, “Come to me, all you who are weary and burdened.” He doesn't give us a time limit or specify certain hours when He is available.
We must understand that the law is setup for us. It is a guide for us to live by, but we need to see the heart behind it. Take the law of the Sabbath for instance. “Work six days and on the seventh day rest.” If you make a habit of working seven days a week and never rest you will wear yourself out and make yourself sick. It is not good and your body cannot handle too much of it.
Jesus wants us to honor the spirit behind the law. He wants us to obey out of Love, not obligation. Jesus Loved God and Loved people. Therefore, when He saw a person suffering on the Sabbath He couldn't stand by and let them suffer. He let Love guide Him to do the right thing. Let Love be your motivator as well.
