A few years back I was profoundly impacted by reading the entire serenity prayer by Reinhold Niebuhr. Most of us have only heard the first four lines, yet the rest of the prayer brings about an important paradigm shift in how we view ourselves, God, and our time on earth. Meditate on this prayer. Ask God to show you how to deposit it deep into your heart so it will become your godly foundation for life.
Prayer for Serenity
God, grant me the serenity
To accept the things I cannot change,
The courage to change the things I can,
And the wisdom to know the difference.
Living one day at a time,
Enjoying one moment at a time;
Accepting hardship as a pathway to peace;
Taking, as Jesus did,
This sinful world as it is,
Not as I would have it;
Trusting that You will make all things right
If I surrender to Your will;
So that I may be reasonably happy in this life
And supremely happy with You forever in the next.
