Kissing in itself is not a sin. If that be the case then those from other countries that kiss the cheek to meet are sinners. I disagree. Depends on what you are kissing for. To casually say hello and greet as they did in the Bible. and also depends on why you are kissing. You don't sin if you just kiss a person. It's when you go past that to other things that lead to sin that is wrong. I am not so judging because Jesus said Judge not and you shall not be judged. Those who judge about a kiss I wonder what they do to sin. ? I think we need to be loving and kind when answering these things and be realistic. I think common sense and good judgment is what God puts into our own hearts and mind. So we should know the difference don't you think. God loves us all and He knows how to show us good from bad right?
