Leviticus 19:18 Do not seek revenge or bear a grudge against anyone among your people, but love your neighbour as yourself. I am the Lord.
Who is your neighbour? That is the first thing we ask when we read s verse like this, and, depending where you are in your relationship with God, your answer will differ...
God does not want to set limits for our relationships, not with Him or with anybody else. The Jews were taught how to refocus on God by keeping to themselves.
Only then did they get sent out by Jesus to tell the rest of the world about God and Jesus.
Love your neighbours by first making sure you love your God and yourself!
