1 John 4:17-18

17That is how we are able to love other people completely. Then, we will not be afraid on the day when God will judge all people. We can be sure that God will not punish us. We know this because we have lived in this world in the way that Jesus lived.

18If we really love God, we will not be afraid of him. We cannot love him completely and also be afraid. We would only be afraid of God if we thought that he would punish us. So, if someone is afraid that God will punish them, it shows that they do not completely know God's love.
