its a vast topic . But there comes a point in our lives when we will all be confronted with a cross roads of whether of not we will follow Jesus or follow self . in fact we will be brought to many crossroads on this issue as God works in us his good will and then allows the work he has done to be tested . What is So important to be a disciple of Jesus is that we cannot love ourselves nor anyone or anything more then we love him . so When he asks of us something .. we obey him. but i have experienced that he is so patient and wants us ALWAYS to succeed . not in our own endeavors ,but succeed in obedience .He never asks us beyond what we are able to do . in his graciousness to us as disciples he often trains us in obedience asking of us small things (as a parent would a young child ) .i.e he might ask a 4 yr old to "pick up his toys " but he wont ask that 4 year old to go to the supermarket for him.. he teaches and we learn obedience . we saw this also with his the first 12 disciples . But within only 2 or so years we see them grow from wide eyed observers to practicing apprentices learning by "DOING" making error and learning some more .Then after only 3 years we see them endued with authority by the Holy spirit within and fully released into a sold our life of obedience even unto death. in all this we must ask - How is it that such a bulk number of those claiming to be his disciples are still sitting mostly inactive in buildings on Sundays 5 ,10 and even 20 years later.. ? imo opinion the main reason is we had been taught to be book students learning the information instead of apprentices learning the trade by practicing it .
