10 So all who believe in the Son of God have this testimony in their own hearts; but those who do not believe God have made him out to be a liar, because they have not believed what God has said about his Son.
11 The testimony is this: God has given us eternal life, and this life has its source in his Son.
12 Whoever has the Son has this life; whoever does not have the Son of God does not have life.
13 I am writing this to you so that you may know that you have eternal life — you that believe in the Son of God.
14 We have courage in God's presence, because we are sure that he hears us if we ask him for anything that is according to his will.
15 He hears us whenever we ask him; and since we know this is true, we know also that he gives us what we ask from him.
16 If you see your brother or sister commit a sin that does not lead to death, you should pray to God, who will give them life. This applies to those whose sins do not lead to death. But there is sin which leads to death, and I do not say that you should pray to God about that.
