1. The Connection of Love in the Spirit
13 By this we know that we abide in him and he in us, because he has given us of his Spirit. 14 And we have seen and testify that the Father has sent his Son to be the Savior of the world. 15 Whoever confesses that Jesus is the Son of God, God abides in him, and he in God. 16 So we have come to know and to believe the love that God has for us. God is love, and whoever abides in love abides in God, and God abides in him. 1 John 4:13-16 (ESV)

13 For in one Spirit we were all baptized into one body—Jews or Greeks, slaves or free—and all were made to drink of one Spirit. 1 Corinthians 12:13 (ESV)

39 Many Samaritans from that town believed in him because of the woman’s testimony, “He told me all that I ever did.” 40 So when the Samaritans came to him, they asked him to stay with them, and he stayed there two days. 41 And many more believed because of his word. 42 They said to the woman, “It is no longer because of what you said that we believe, for we have heard for ourselves, and we know that this is indeed the Savior of the world.” John 4:39-42 (ESV)

2. The Confidence of Love for the future
17 By this is love perfected with us, so that we may have confidence for 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. For fear has to do with punishment, and whoever fears has not been perfected in love.
1 John 4:17-18 (ESV)

10 Why do you pass judgment on your brother? Or you, why do you despise your brother? For we will all stand before the judgment seat of God; 11 for it is written, “As I live, says the Lord, every knee shall bow to me, and every tongue shall confess to God.” 12 So then each of us will give an account of himself to God. Romans 14:10-12 (ESV)

10 For we must all appear before the judgment seat of Christ, so that each one may receive what is due for what he has done in the body, whether good or evil. 2 Corinthians 5:10 (ESV)

3. The Command of Love to the saint
19 We love because he first loved us. 20 If anyone says, “I love God,” and hates his brother, he is a liar; for he 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: whoever loves God must also love his brother.
1 John 4:19-21 (ESV)

36 “Teacher, which is the great commandment in the Law?” 37 And he said to him, “You shall love the Lord your God with all your heart and with all your soul and with all your mind.38 This is the great and first commandment.39 And a second is like it: You shall love your neighbor as yourself.40 On these two commandments depend all the Law and the Prophets.” Matthew 22:36-40 (ESV)
