Luther on The Lord's Supper

When we have received the Lord's Supper we should give special attention to love. In this way we assure that we have received the sacrament in the manner intended and at the same time provide evidence to others. We cannot always come and still continue unchanged; therefore, we must turn from our devotions and thoughts of our conduct toward our neighbor and examine ourselves in this mirror with all seriousness. The sacrament is to act upon us so that we may be transformed and become different people. God's word and work do not intend to be idle but are bound to produce great things. The Word and work should set us free from sin, death, the devil, and every kind of fear. The Word and work should make us servants even of the least among men on earth without the slightest complaint on our part. We should rejoice to find someone in need of our help and fear only after being blessed so much we might not find means to use it all to help others.

Whenever the Lord's Supper fails to produce this result there is reason to fear it has caused harm. Even so, if the result is not great, we should not reject those that are imperfect and weak; however, we should reject those that are inactive and disrespectful and imagine they have done enough when they have participated in the sacrament. A change must take place in you that results in a life that provides evidence for that change. Then when you share in the Lord's Supper you will be able to perceive that God is with you and your faith will grow sure and strong. You can easily feel whether you have grown more joyous and bold than you were before. Previously, the world seemed too narrow for us when we heard of death and thought of sin. Now, we might feel different but it is not because of our own strength. In the past we could not get so far although we worked harder and tried to help ourselves by means of works. Likewise, you can feel whether you are kind to those who have injured you and whether you are merciful to those who are sick. Through your feelings you can discover whether the Lord's Supper is producing any fruit through your life. If you experience nothing, go to God and tell him of your shortcomings and troubles. We all must do the same thing as long as we live for none of us are perfect.
