Love is to be the interpreter of law. Where there is no love, these things are meaningless, and law begins to do harm.
"One Sabbath, when he went to dine at the house of a ruler of the Pharisees, they were watching him carefully. And behold, there was a man before him who had dropsy. And Jesus responded to the lawyers and Pharisees, saying, “Is it lawful to heal on the Sabbath, or not?” But they remained silent. Then he took him and healed him and sent him away. And he said to them, “Which of you, having a son or an ox that has fallen into a well on a Sabbath day, will not immediately pull him out?” And they could not reply to these things." (Luke 14:1-6)
Faith is here set forth in that this man, sick with the dropsy, looks to Christ and firmly believes he will help him. This faith he had as the result of his previous acquaintance with Jesus. He knows him as a kind, friendly and sympathetic man who always helps everyone and lets none go away uncomforted. Had he not heard such reports about the Lord he would not have followed him, even into the house. He must indeed have had some gospel knowledge and believed the wonderful things spoken about him.
And this is the Gospel, that must be preached and heard before there can be faith. We must know that God is kindly disposed toward us and has sent his Son from heaven to help us. This the conscience must hear and believe; for if God were unfriendly and unmerciful toward us, it would avail little to know that all his creatures sympathize with us. If God is satisfied with us, no creature can do us any harm, as St. Paul says in Rom. 8:31 ”If God is for us, who is against us?” Let death, devil, hell, and all creation rage; we are safe. Therefore, it is the Gospel that must present to us the God-man as merciful. This is the fountain from which our heart can draw faith and a friendly confidence toward God that he will help both the dying and the living in every distress.
We notice this here in the man afflicted with dropsy. He had heard of the kindness of Jesus to others and now believes that he will show the same to him. Had he not believed, it would have been impossible to help him. The Gospel resounds in all the world, but it is not heard by everybody. The Pharisees also sat there; they saw these things with their own eyes and failed not to notice what a friendly man Jesus was, but they believed not; hence the Gospel could neither reform them nor give them help and comfort. Thus the Gospel is very universal, but the true laying hold of it is very rare. So much in regard to faith.
Later we have here pictured to us also the love in Christ that goes forth and bears fruit, not for itself but for others, as is the nature of true love to do. However, this Periscope especially teaches us in the second place a necessary doctrine we must possess, if we are to make use of the laws that order the outward and temporal matters and affairs, which the church is to observe. Here we must act wisely and gently, if we wish to do the right thing, especially when weak and timid consciences are concerned. For there is nothing more tender in heaven and on earth, and nothing can bear less trifling, than the conscience. The eye is spoken of as a sensitive member, but conscience is much more sensitive. Hence we notice how gently the Apostles dealt with conscience in such matters, lest it be burdened with human ordinances.
But as we cannot live without law and order, and as it is dangerous to deal with law since it is too apt to ensnare the conscience, we must say a little about human laws and ordinances and how far they are to be observed. The proverb says: “Everything depends upon having a good interpreter.” That is particularly true here where human ordinances are concerned. Where there is no one to interpret and explain the law rightly it is difficult and dangerous to have anything to do with it. Take, for example, a ruler who acts like a tyrant and abuses his authority. If he makes a law and urgently insists on the law being executed, he treats conscience as if he had a sword in his hand and were intent on killing. So there is great danger where one does not know how to temper and apply the laws.
Therefore, we conclude that all law, divine and human, treating of outward conduct, should not bind any further than love goes. Love is to be the interpreter of law. Where there is no love, these things are meaningless, and law begins to do harm. The reason for enacting all laws and ordinances is only to establish love, as Paul says, Rom. 13, 10: ”Love therefore is the fulfilment of the law.” Likewise verse 8: ”Owe no man anything, save to love one another.” For if I love my neighbor, I help him, protect him, hold him in honor, and do what I would have done to me. Since then all law exists to promote love, law must soon cease where it is in conflict with love.
