We shall love the Lord our God with all our heart, and with all our soul, and with all our mind. This is the first and greatest commandment. The second is like it. We shall love our neighbor as ourselves. On these two commandments depend the whole law and the prophets. Therefore, we will go into all the world and preach the good news to all creation. We are not ashamed of this good news about Messiah, for it is the power of God at work, saving everyone who believes, Jews first, and also non-Jews.
