Our Christian walk should have a purpose and therefore each of us has one. Some might say that they don't understand what that purpose is but fundamentally we all have AT LEAST one that is very basic: become more like Christ and displaying that example to the world each day. There are other branches and extensions of our purpose, but that one is common to each of us who have put on Christ.
Procrastination and inaction are simply a measure of your purposefulness. Here is how they are connected. I'll use a familiar example to which we can all relate. Someone in our family is responsible for providing for it. That is a purpose. Now imagine if the way by which they did that was through going to work each day and when they do not work, they do not have the means by which to fulfill that purpose. In those circumstances, how often do you believe the person that has that purpose would procrastinate or not take action to fulfill that purpose, i.e. not go to work? Probably not often. Procrastination and inaction are not acceptable in this case because the purpose is VERY clear. Now, so are the consequences, but are you driven by a purpose or by consequences?
What if you believed in the purpose of your Christian walk with the same level of criticality as the person providing for their family? Shouldn't you believe in it with the same criticality? If you did, what procrastination and inaction would you accept?
The sources of inaction and procrastination in our Christian walk takes on many forms, too many for me to name here. However, some of those sources are fear, insufficient faith, misplaced faith (meaning faith only in ourselves), numerous excuses, and the lack of accountability. The list can go on and on. That's why it's important to believe in YOUR purpose in God's kingdom. We all have a common one. With that belief, you should then DAILY put into action the multiple things that will help you live out that purpose.
Yours in Christ,
Adrian
