Our greatest lessons come out of pain,

and the Bible says God keeps a record of our tears.

Whenever problems occur,

remember that God uses them

to fulfill all five purposes in your life;

Problems force you to focus on God,

draw you closer to others in fellowship,

build Christlike character,

provide you with a ministry,

and give you a testimony.
Every problem is purpose-driven.

- Rick Warren
