Many a teenager has had a sip of alcohol before they were legally allowed to drink but for some that sip leads to eventually a shot. Where does one error of judgement lead someone down a path of destruction? Why will some learn to do things in moderation while others will fall through the cracks.
There are many factors that cause this downfall including a genetic component but I believe that the greatest factor is self worth. If a person understands that they are just human and are subject to sin ( once in awhile) then they can accept their mistakes ask for forgiveness and move on. If on the other hand a person doesn’t have this confidence they might believe it’s already too late, so why not keep enjoying the moment even when it becomes more and more difficult to achieve.
Those that don’t have faith will continue to struggle because they don’t truly see a path to true forgiveness and salvation. Not every path is clear and simple, there might be roadblocks along the way but if we truly believe in a divine purpose we all will get there one step at a time. G-D allows us to slip and lends a helping hand as long as we try to keep on that path. Try telling a friend, family member that is struggling that you’ll be that helping hand here when they need it but first they truly must grasp it.
