In the light of the resurrection of Christ, the Christian who loves the church has assurance of their salvation and they should have no fear of God’s coming judgment of sinners.
16b God is love, and the one who abides in love abides in God, and God abides in him.
17 By this, love is perfected with us, so that we may have confidence in the day of judgment; because as He is, so also are we in this world.
18 There is no fear in love; but perfect love casts out fear, because fear involves punishment, and the one who fears is not perfected in love.
19 We love, because He first loved us.
20 If someone says, “I love God,” and hates his brother, he is a liar; for the one who does not love his brother whom he has seen, cannot love God whom he has not seen.
21 And this commandment we have from Him, that the one who loves God should love his brother also.
