If you fail under pressure, your strength is too small.
Proverbs 24:10 NLT
Read Proverbs 24:10.
Take some time and examine what is sapping your strength (life, pain, suffering and age are some reasons). What would change if we made a change from self-reliant (Habakkuk 1:11) to God-reliant (Jeremiah 17:5-8)?
