Here's a short take on how Biblical friendship really works:
John15:12-15- Jesus view of friendship
12 This is my commandment: Love each other in the same way I have loved you. 13 There is no greater love than to lay down one's life for one's friends. 14 You are my friends if you do what I command. 15 I no longer call you slaves, because a master doesn't confide in his slaves. Now you are my friends, since I have told you everything the Father told me.
How to love - 1 Corinthians 13: 4-7
4 Love is Patient (don't be annoyed or anxious) and Kind (generous or considerate). Love is Not Jealous (showing envy of someone or their achievements and advantages) or Boastful (self-satisfaction in one's achievements, possessions, or abilities) or Proud (having or showing a high or excessively high opinion of oneself or one's importance) 5 or Rude (offensively impolite or ill-mannered). It does Not Demand Its Own Way. It is Not Irritable (easily annoyed or made angry), and it Keeps No Record of Being Wronged. 6 It does Not Rejoice about Injustice but Rejoices Whenever the Truth Wins Out. 7 Love Never Gives Up, Never Loses Faith, is Always Hopeful, and Endures Through Every Circumstance.
A Biblical example (David and Samuel) - 1 Samuel 18: 1-3
1 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. 2 From that day on Saul kept David with him and wouldn't let him return home. 3 And Jonathan made a solemn pact with David, because he loved him as he loved himself.
