If I lose a friend, this can be because we both need to learn better how to love. So, I can offer myself to God for His correction which will make me more able to really love any and all people, not to only pick and choose who I want to use.
"For if you love those who love you, what reward have you?" (in Matthew 5:46)
And I find that God has me deal with forgiving those who do not forgive me. And we all need
"longsuffering" in our relating with each other >
"with all lowliness and gentleness, with longsuffering, bearing with one another in love," (Ephesians 4:2)
Even our really good friends and leaders can at times be wrong, somehow; so we need to keep
"longsuffering" ready . . . so we don't trash a good friendship or leader because of some one thing . . . or even more than one thing
"Also, we need to not give up on someone because of a problem we have with the person; because we imperfect can misunderstand someone. In God's loving, things can be
'past finding out' (Romans 11:33) so we do not understand what someone is doing to love us, and our selfish nature can get into things and have us taking things the wrong way."
"So, do not trust any thinking or reacting or decisions or ways of seeing things, which are not in the ruling of God's peace in us."
"And let the peace of God rule in your hearts, to which also you were called in one body; and be thankful." (Colossians 3:15)
So, never mind how you might expect someone else to love you; we have our own correction to seek from God. If a person fails to love and forgive you . . . trust the person to God, and keep having hope for the person > love
"hopes all things" (in 1 Corinthians 13:7).
Jesus never gave up on any of His disciples. So, we know He does not give up on us. But He desires that we appreciate this . . . by following His example
