This is one good question someone ask. My straight answer to him is no. Our bad stuff get worst. Don't you agree? If we are lazy, in due time, we become lazier. It seen like our chances of becoming good is only up to Army time or to the girls, JC time. After that, I can't remember if any of us got any scolding from any one due to our bad habits or that anyone would "discipline" us. Even my parents don't, and when they pass away, all the more I am a free man.
And if we did not buck up during the time of discipline, and get over our bad habits, we do not seen to have a chance to resolve that. Yet, it is in those time, we constantly think of ways to get out of the discipline time.
So how can we claim a promise that it is in Christ we change. Simple actually, we have to subject ourselves to His discipline. But what would we expect? Most of us thought we would expect a lightning strike...but actually the real lightning comes from our loved one. For God will use Man to wake us up. Man that we thought are inferior to us to humble us and make us realise how proud we was that no one can discipline us.
