I am talking about the single breath that we take each moment, which sustains our physical lives. We have absolutely no control as to when it will end yet we live as if it will last forever.
Just as easily as the presence of one breath of air keeps us alive, the absence of one breath of air can transport us into the eternal world of the dead. Hence, we are always but a breath away from death.
This knowledge of the difference one breath of air can make should cause us to strive to live at peace with everyone, as much as it is possible to do so.
This knowledge of the difference one breath of air can make should also cause us to examine ourselves on a daily basis, to make certain that we are living our lives in accordance to the standard set by God in His word.
Don't bother comparing yourself to anyone else because one imperfect human being will just be comparing him/herself to another imperfect human being and whatever the results are, they will be useless.
Compare yourself to God's standard as outlined in His word and then you will be able to make true progress.
