If you see someone in error. You turn them away from error. Thats how you love someone.
Yes, the wife showed love she forgave unconditionally. As God loves, But you do not want to focus on that, you want to focus on the sin and the sinner, Well unless its your own sin, which you excuse the easy way with 1 John
Your right, he will not, He will chasten them and get them back in line.
What he will not do is kick them out of his family, He adopted them, they did not adopt him. To ckick them out, he would not be loving.
of course, I forgot, you don't understand what true love is. I can only pray you do not treat your wife and kids they you you say God treats us.
