Philippians 1:9-10 (ESV)
9 And it is my prayer that your love may abound more and more, with knowledge and all discernment, 10 so that you may approve what is excellent, and so be pure and blameless for the day of Christ,
2 Corinthians 8:7 (ESV)
7 But as you excel in everything—in faith, in speech, in knowledge, in all earnestness, and in our love for you — see that you excel in this act of grace also.
1 Thessalonians 3:12 (ESV)
12 and may the Lord make you increase and abound in love for one another and for all, as we do for you
Matthew 20:20-28 (ESV)
20 Then the mother of the sons of Zebedee came up to him with her sons, and kneeling before him she asked him for something. 21 And he said to her, “What do you want?” She said to him, “Say that these two sons of mine are to sit, one at your right hand and one at your left, in your kingdom.” 22 Jesus answered, “You do not know what you are asking. Are you able to drink the cup that I am to drink?” They said to him, “We are able.” 23 He said to them, “You will drink my cup, but to sit at my right hand and at my left is not mine to grant, but it is for those for whom it has been prepared by my Father.” 24 And when the ten heard it, they were indignant at the two brothers. 25 But Jesus called them to him and said, “You know that the rulers of the Gentiles lord it over them, and their great ones exercise authority over them. 26 It shall not be so among you. But whoever would be great among you must be your servant, 27 and whoever would be first among you must be your slave, 28 even as the Son of Man came not to be served but to serve, and to give his life as a ransom for many.”
John 13:1-5 (ESV)
13 Now before the Feast of the Passover, when Jesus knew that his hour had come to depart out of this world to the Father, having loved his own who were in the world, he loved them to the end. 2 During supper, when the devil had already put it into the heart of Judas Iscariot, Simon's son, to betray him, 3 Jesus, knowing that the Father had given all things into his hands, and that he had come from God and was going back to God, 4 rose from supper. He laid aside his outer garments, and taking a towel, tied it around his waist. 5 Then he poured water into a basin and began to wash the disciples' feet and to wipe them with the towel that was wrapped around him.
