Where is our Security

I think when we look at the book of Mark Ch 10:46-52 and study the life of Bartimaeus.... not only his faith healed him .... Jesus tells him ur faith has healed you... but he also throws his coat and follows Jesus. What's so special about the coat??? well that was his only source of income..... and he gave it all up to do what Christ had in store for him...... lets divert a little and look at the disciples ... Peter, James and John were fishermen and they threw their fishing nets to follow Jesus..... my question here is .... what are you and I ready to give up for Christ..... where is our security??? is it in our job, is it in our bank balance, is it our finances, is it our family...... or are we ready to leave all worries aside and follow Jesus trusting him completely..... believing that He would take care of everything else..... r you and I willing to give our all to the furtherance of His Kingdom.... especially with the economic doom threatening...
