Because God loved us
In no way did we deserve the love that God lavished upon us when He sent Jesus to die for our sins. We seek to be a conduit of that same love to those that God places in our path.
"but God shows his love for us in that while we were still sinners, Christ died for us." (Rom 5:8)
Recognizing we are equal before the cross
We are all in need of the grace of God and we are all equally in need of the sacrifice of Christ. When we look at others, it is only pride that believes that "I am better than them," because that is not how God views our standing before HIm. We were all born in sin and by nature were enemies of God. It is only by His mercy that we have hope of a right relationship with God and are destined to our eternal hope, heaven.
"But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved." (Eph 2:4-5)
Christ provided the perfect example of how to love those around Him. His love was so extravagant, that he was willing to lay down His life for them. We desire to demonstrate this sacrificial love, as we seek to be like Jesus
"A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another." (John 13:34)
Living out Christ to others
Looking for redemptive moments
The love that God gave to us is a an active love, a redemptive love. It is always on mission to reconcile people to God. As we love others, we look for ways share the gospel and live like Christ in the moment.
"Therefore, we are ambassadors for Christ, God making his appeal through us. We implore you on behalf of Christ, be reconciled to God. For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God." (2 Cor 5:18-20)
Not seeking something in return
Our hearts are drawn to the "what's in it for me?" mentality in relationships. This only leads to disappointment and insincerity in our love for others. We are committed to loving people in worship to God without seeking something selfishly in return.
"Religion that is pure and undefiled before God the Father is this: to visit orphans and widows in their affliction, and to keep oneself unstained from the world." (James 1:27)
Our love for others is an overflow of the love that God demonstrated to us. As we grow in our love for God and in our understanding of His character, our love for people will grow more and more. This changes our relationships, families, communities, and churches
"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. This is the great and first commandment. And a second is like it: You shall love your neighbor as yourself. On these two commandments depend all the Law and the Prophets.” (Matt 22:37-40)
