You can still love another person without abandoning them.
What God said 120 years prior to the great flood.
The Early church was told by the apostles to “Release(non repenting sinning Christians) them unto Satan, until such time they should repent”.
Sometime love demands we abandon erring ones, especially if such erring may threaten other innocent ones either as direct physical threats or indirectly thru influencing the innocents to commit sin themselves.
There is a time one must let go for the sake of one’s own spiritual integrity. One can mistake spiritual integrity for “wounded pride”, but “wounded pride” may also cause a parent or loved one to cling to an erring one to such an extent, that the erring one has no motivation to examine him or herself and to change those behaviors that are in error. “Tough love” maybe the only radical spiritual scalpel that may yet save the patient from him or her self!
