When you live for the purpose of making a difference for the people, for society, for the things that are beyond you, then significance will not be able to elude you.
Finding meaning for life is simply coming into significance because you have been able to accomplish and fulfill your purpose.
If you have committed all things to impacting a life at a time, or impacting a community or society, then welcome to a life of significance.
It is a good thing to live long but it is much more important to make a difference in life by living a life of significance.
The only reason for your intimidation by the devil, and your being afraid of him, or what he can do is because you are living in ignorance (darkness) which is his territory.
A person could waste an important part of his living if he refuses to come into significance; if he refuses to impact lives around, the family and in the community or in the society.
The truth is that if you do not join the way of godliness, then you do not have any reason to complain when the ungodly are busy planning and making the pathway of ungodliness.
