Love should always be unconditional that is the nisayon of a parent. It is a test. Hashem does not give you the gift of children with conditions. Love this child only if s/he is good and only if s/he listens to me and you. Cast them away if they don’t. Does Hashem cast US away if we don’t listen to HIM? Does Hashem stop loving us? Or does HE always give us the opportunity to do Teshuva and return??????
Hashem loves US unconditionally and we must learn from that. WE must love our children unconditionally. We don’t have to like what they are doing or approve of what they are doing but we love them unconditionally, no strings attached. They are still OUR children born to us, a gift from Hashem and we never, ever take that gift for granted. To do so would be to spit in the face of Hashem!!!! We NEVER ever give up on our children. We love them and we daven for them always and forever.
