Ladies, if we love our children then smacking isn't an option, it's our duty as loving parents to discipline our children when they need it in order to drive out the rebellion which as human beings is sadly in us from birth. Can you ever remember teaching your toddler to throw tantrums? Of course not, but everyone of them could be awarded a BAFTA for their performances of choking, convulsions, emotional blackmail, aggression etc.
The bible, teaches - "Whoever spares the rod hates their children,but the one who loves their children is careful to discipline them." Proverbs 13:24.
Discipline isn't violence, because there isn't, or at least shouldn't be, any malice involved, in fact the quite the opposite - smacking is an expression of parental love.
In our house the rule has always been that spanking is reserved for two 'crimes', lying and rebellion. Accidents which lead to things being broken - whatever the value - have never been punished by spanking because they weren't deliberate. The state has the power and authority to punish those caught 'going prepared' to commit a crime. The law rules that it is the intent which is the primary factor in determining guilt, the act merely follows. (except 'strict liability' crimes of course)
The real test that we should apply before chastising our children is - What is my motive? Is it anger, frustration or love? If it's the first then you need to ask your children to forgive you because you have effectively abused them and that does cause real damage. If it's love then they will be very grateful that you are doing what is right for them
I hope that helps for you mums and dads who feel conflicted over the issue.
God bless you.
