After David had finished talking with Saul, he met Jonathan, the king’s son. There was an immediate bond between them, for Jonathan loved David. From that day on Saul kept David with him and wouldn’t let him return home. And Jonathan made a solemn pact with David, because he loved him as he loved himself. Jonathan sealed the pact by taking off his robe and giving it to David, together with his tunic, sword, bow, and belt.
1 Samuel 18:1‭-‬4 NLT

So now I am giving you a new commandment: Love each other. Just as I have loved you, you should love each other. Your love for one another will prove to the world that you are my disciples.”
John 13:34‭-‬35 NLT

This is real love—not that we loved God, but that he loved us and sent his Son as a sacrifice to take away our sins. Dear friends, since God loved us that much, we surely ought to love each other.
1 John 4:10‭-‬11 NLT

We can see how Jonathan in 1 Samuel chapter 18-20 loved David dearly and even intervened on David’s behalf with his father. What friendship and love we can see here!

And even moreso, what friendship and love we can see in Jesus doing the same, even greater, for us!

There is no greater love than to lay down one’s life for one’s friends.
John 15:13 NLT

“I am the good shepherd; I know my own sheep, and they know me, just as my Father knows me and I know the Father. So I sacrifice my life for the sheep. I have other sheep, too, that are not in this sheepfold. I must bring them also. They will listen to my voice, and there will be one flock with one shepherd. “The Father loves me because I sacrifice my life so I may take it back again. No one can take my life from me. I sacrifice it voluntarily. For I have the authority to lay it down when I want to and also to take it up again. For this is what my Father has commanded.”
John 10:14‭-‬18 NLT

So then, since we have a great High Priest who has entered heaven, Jesus the Son of God, let us hold firmly to what we believe. This High Priest of ours understands our weaknesses, for he faced all of the same testings we do, yet he did not sin. So let us come boldly to the throne of our gracious God. There we will receive his mercy, and we will find grace to help us when we need it most.
Hebrews 4:14‭-‬16 NLT

Who dares accuse us whom God has chosen for his own? No one—for God himself has given us right standing with himself. Who then will condemn us? No one—for Christ Jesus died for us and was raised to life for us, and he is sitting in the place of honor at God’s right hand, pleading for us. Can anything ever separate us from Christ’s love? Does it mean he no longer loves us if we have trouble or calamity, or are persecuted, or hungry, or destitute, or in danger, or threatened with death? (As the Scriptures say, “For your sake we are killed every day; we are being slaughtered like sheep.” ) No, despite all these things, overwhelming victory is ours through Christ, who loved us. And I am convinced that nothing can ever separate us from God’s love. Neither death nor life, neither angels nor demons, neither our fears for today nor our worries about tomorrow—not even the powers of hell can separate us from God’s love. No power in the sky above or in the earth below—indeed, nothing in all creation will ever be able to separate us from the love of God that is revealed in Christ Jesus our Lord.
Romans 8:33‭-‬39 NLT
