Plilippians 1 "Strenghth"

When you show strength you are not only doing it for you benefit it also brings others up, same for weakness, you are making it ok for others to be weak and making them less bold to speak about Christ.  

Even if you must put on a front it is better, not the best but better, than not sharing God's word.  True strength comes from the father and through Him life is worth living.
