When we reconcile with our brethren, we receive a temporary peace, our peace of mind. But what Jesus offers us is much more. It is the ultimate peace in our hearts, knowing that our broken relationship with The Father has been fixed by His death on the cross.
Jesus and John, both preached in a similar manner but their lifestyles were different. The former lived a normal life and the latter lived in the wilderness. However, not many people took their message. Maybe people went to John not to repent or to get baptized but to see how was he living and similarly, people might have gone to hear Jesus not because they wanted to know his message but probably to find fault in him.
