There are varying degrees of relationship, which call for varying degrees of trust. Not everyone is allowed to know me intimately, just as I am not able and do not have the capacity to know everyone intimately. There are people I have met and those I will never meet who feel they know me and my colleagues via YouTube and social media. It would not be wise to trust anyone and everyone with the information and experiences I share with my confidants. However, I love everybody, as everyone is my neighbor. 

Jesus had throngs of people around Him as He preached in the region, most of whom He did not know. Many followed Him, including men and women, and because He healed, preached, and taught them, they felt a false sense of closeness to Him. Moreover, the Bible documents that Jesus sent out 70 into the regions with instructions to prepare the way for Him. He called 12 to help with His ministry, teaching and preparing them to take up the mantle behind Him. Out of the 12, there were only three in His inner circle: Peter, James, and John. He granted them access to witness His struggles in ministry, His transfiguration, and become His confidants. Notice that each group became smaller. Although there were degrees of trust and access, Jesus loved everyone and showed His love by going to the cross. 

We are commanded to love everyone as we love ourselves, even our enemies. Healthy love does not want to see harm come to another because we would not want harm to come to ourselves. There are no degrees of love, just types of love. One can love others as neighbors/strangers, friends, enemies, family, or romantically, but the foundation is the same. Love your neighbor as yourself.
