 Beware, if you are thinking, that you have nothing to change in yourself or no need to do so:
such thought means, that you have stopped transform to Christ's image.
Beware, if you are doing nothing for transforming yourself, when you see what should be changed:
time is deceptive, and you quickly will find lies for yourself, to hide the problem.

As long, as you are changing - you are alive.
In the moment, when you will stop to do it - you are as well as dead:
time is deceptive, and after many years, when you'll find that you are the same person as you was, you'll understand, that those years were empty and blind.
He teaches us to grow all the time, and there is no end for this process here.
