Living according to the will of God: "Because we live like Jesus here in this world," 1 John 4:17
The will of God is that we perfect ourselves in love:
"And we have known and believed the love that God has for us. God is love, and he who abides in love abides in God, and God in him.
And as we live in God, our love grows more perfect. So we will not be afraid on the day of judgment, but we can face him with confidence because we live like Jesus here in this world.
