2 He gave his life to pay for our sins. But he not only paid for our sins. He also paid for the sins of the whole world.
3 We know that we have come to know God if we obey his commands.
4 Suppose someone says, "I know him." But suppose that person does not do what God commands. Then that person is a liar and is not telling the truth.
5 But if anyone obeys God's word, then God's love is truly made complete in that person. Here is how we know we belong to him.
6 Those who claim to belong to him must live just as Jesus did.
7 Dear friends, I'm not writing you a new command. Instead, I'm writing one you have heard before. You have had it since the beginning.
8 But I am writing what amounts to a new command. Its truth was shown in how Jesus lived. It is also shown in how you live. The darkness is passing away. The true light is already shining.
