1. The Lord is one (28-34)
Jesus answered a teacher of the law, saying that the most important commandment is to know God as the Sovereign Lord of the universe. He is the only God. Therefore, we should love him with all our heart, with all our soul, with all our mind, and with all our strength (Deut 6:5). We then should love our neighbor as ourselves too. But still, Jesus said to the teacher of the law who knew this very well, 'you are very near to the kingdom of God.' It is because no one can keep God's command. All must come to Jesus and be forgiven to enter the kingdom of God.
2. Jesus, the Lord of David (35-37)
Here Jesus further revealed who he was. He was a son of David, the promised Messiah. Therefore, he is the Lord of David. The teacher of the law must know Jesus as the Lord, the only God who would die for him. We can enter the kingdom of God not by keeping the command but by faith in Jesus, the Lord, who died for our sins and was raised from the dead to give us eternal life in the kingdom of God.
