Humbly Serve Others Loving Them Sacrificially

John 13:12-17 When Jesus had washed their feet and put on His outer robe, He sat down again and told them, "Do you realize what I have done to you? You call me Teacher and Lord and you are right because that is what I am. So if I, your Lord and Teacher, have washed your feet, you must also wash one another's fee. I have set an example for you, so that you may do as I have done to you. Truly I tell all of you emphatically, a servant is not greater than his master, and a messenger is not greater than the one who sent him. If you understand these things, how blessed you are if you put them into practice!

John 15:9-14 Just as the Father has loved me, so I have loved you. So abide in my love. If you keep my commandments you will abide in my love, just as I have kept my Father's commandments and abide in His love. I have told you this so that my joy may be in you, and that your joy may be complete. This is my commandment: that you love one another as I have loved you. No one shows greater love than when he lays down his life for his friends. You are my friends if you do what I command you.

1 John 4:7-21 Dear friends, let us continually love one another, because love comes from God. Everyone who loves has been born from God and knows God. The person who does not love does not know god, because God is love. This is how God's love was revealed among us: god sent His unique Son into the world so that we might live through Him. This is love: not that we have loved God, but that He loved us and sent His Son to be the atoning sacrifice for our sins. Dear friends, if this is the way God loved us, we must also love one another. No one has ever seen God. If we love one another, God lives in us, and His love is perfected in us. This is how we know that we abide in Him and He is us: He has given us His Spirit.
We have seen for ourselves and can testify that the Father has sent His Son to be the Savior of the world. God abides in the one who acknowledges that Jesus is the Son of God, and he abides in God. We have come to know and rely on the love that God has for us. God is love, and the person who abides in love abides in God and God abides in him.
This is how love has been perfected among us: we will have confidence on the day of judgment because, during our time in this world, we are just like Him. There is no fear where love exists. Rather, perfect love banishes fear, for fear involves punishment, and the person who lives in fear has not been perfected in love.
We love because God first loved us. Whoever says, "I love God," but hates his brother is a liar. The one who does not love his brother whom he has seen cannot love the God whom he has not seen. And this is the commandment that we have from Him: the person who loves God must also love his brother.
