There are often times in our lives when we feel exceptionally weak. It may not be due to a physical impairment, but simply because life overwhelms us.
It is at such times when we need an encouraging Bible verse, such as this one from the book of Isaiah:
Do not fear: I am with you;
Isaiah 41:10
do not be anxious: I am your God.
I will strengthen you, I will help you,
I will uphold you with my victorious right hand.
